Velad pues, porque no sabéis cuándo el señor de la casa vendrá; si á la tarde, ó á la media noche, ó al canto del gallo, ó á la mañana;
assim também vigiai, porque não sabeis quando virá o Senhor da casa; se à tarde, se à meia-noite, se ao cantar do galo, se pela manhã,
Veillez donc, car vous ne savez quand viendra le maître de la maison, ou le soir, ou au milieu de la nuit, ou au chant du coq, ou le matin;
So wachet nun ( denn ihr wißt nicht, wann der Herr des Hauses kommt, ob er kommt am Abend oder zu Mitternacht oder um den Hahnenschrei oder des Morgens),
Zo waakt dan (want gij weet niet, wanneer de heer des huizes komen zal, des avonds laat, of ter middernacht, of met het hanengekraai, of in den morgenstond);
Vegliate dunque perché non sapete quando viene il padron di casa: se a sera, a mezzanotte, o al cantar del gallo la mattina;
Czujcież tedy; (bo nie wiecie, kiedy Pan domu onego przyjdzie, z wieczorali, czyli o północy, czyli gdy kury pieją, czyli rano.)
Итак бодрствуйте, ибо не знаете, когда придет хозяин дома: вечером, или в полночь, или в пение петухов, или поутру;
所以，你們要警醒；因為 你們不 知道 家 主 甚麼時候 來，或 晚上，或 半夜，或 雞叫，或 早晨；
So you are to keep watch: because you are not certain when the master of the house is coming, in the evening, or in the middle of the night, or at the cock's cry, or in the morning;

Scholars' Consensus
Commentators across traditions agree that Mark 13:35 issues a direct command to vigilance grounded in the uncertainty of Christ's return. The Greek verb γρηγορεῖτε (grēgoreite) carries the force of a present imperative: keep on being alert. Vincent's Word Studies distinguishes it from the word translated “keep alert” in verse 33, noting that γρηγορεῖτε adds the idea of a sleeping person rousing himself, not merely staying awake but actively alert. Adam Clarke emphasizes that the more the master is expected, the more diligent the servants should be in working and watching. Barnes identifies the “master of the house” as Jesus himself, returning at an unexpected hour. The four time markers, evening, midnight, cockcrow, morning, correspond to the four Roman watches of the night, as Jamieson-Fausset-Brown and others observe. The Cambridge Bible for Schools and Colleges links the passage to Temple practice: the superintending priest might knock at the door at any moment, and the night sentinels had to be ready. Both Gill and the Cambridge commentary note that the Rabbis used almost the same language to describe the unexpected coming of the master. The consensus is clear: watchfulness means living each day in readiness, because the Lord's return will come as a surprise.
How settled is the interpretation?
Interpretive difficulty: Medium
Main views:
- First-century fulfillment view: Verse 30 'this generation shall not pass' suggests the coming refers to the destruction of Jerusalem in AD 70; the night watches picture the sudden arrival of judgment on the temple system (Gill).
- Future second coming view: Verse 32 pushes the time to an unknown day and hour far beyond that generation; the context highlights the final return of the Son of Man, applicable to all believers (Barnes, Vincent).
What is clear: The command to watch is unconditional and applies to all believers awaiting the Lord's return, regardless of the exact referent.
What Scholars Agree and Debate
| Topic | Agreed | Debated |
|---|---|---|
| Meaning of 'watch' (γρηγορεῖτε) | All traditions agree the verb calls for active, ongoing alertness, not passive waiting. | Some stress mental vigilance (doctrine, warning against false teachers), while others emphasize practical obedience and daily work. |
| Identity of the master's coming | The master is Christ; his coming is certain but the time unknown. | Whether the coming refers specifically to the destruction of Jerusalem in AD 70 (as a judgment on the Jewish nation) or to the final second coming at the end of history. Both views find support in the discourse. |
| Application of the night watches | The four watches cover the entire night, symbolizing that no time is exempt from the call to watch. | Some see the watches as literal times of the night, while others allegorize them as stages of life (childhood, youth, adulthood, old age) or periods of church history. |
Historical & Cultural Context
Jesus spoke these words from the Mount of Olives, seated opposite the temple (Mark 13:3). The discourse in Mark 13 responds to the disciples' questions about the destruction of the temple and the signs of the end. Verse 35 concludes a parable about a man going on a journey, leaving his servants in charge and commanding the doorkeeper to watch (vv. 34-37). The immediate audience would have seen themselves in that story. The “master of the house” is Christ himself (Barnes).
The four time markers, evening, midnight, cockcrow, morning, reflect the four Roman watches of the night, which by the first century had replaced the earlier three-watch Jewish system. Mark 6:48 shows Jesus walking on the water during the fourth watch, confirming this usage. The imagery draws directly from the temple's nightly procedure, as the Cambridge Bible points out. In the Mishnah (Tamid 1.1-2), the priest in charge of the night sentinels of the Levitical guard would come unexpectedly, knock on the door, and the guards had to rise and open for him. The Rabbis said: “Sometimes he came at the cockcrowing, sometimes a little earlier, sometimes a little later. He came and knocked, and they opened to him.” Jesus uses this familiar routine to illustrate alertness for his return.
Gill's Exposition provides extensive rabbinic evidence for the four watches, including the phrasing “cock crowing” and “morning” as distinct periods. The word ἀλεκτοροφωνίας (alektorophōnias) specifically means “cock-crowing,” a term used for the third watch of the night (Thayer). The watches represented not just time but spiritual readiness: each watch demanded attentiveness, as the captain could appear at any moment. This context transforms a simple time reference into a call for constant, uninterrupted watchfulness.
Textual Notes
The consulted sources note no significant textual variants for this verse. The Greek text is stable across major manuscripts. The verb γρηγορεῖτε appears consistently in the present imperative, and the four time adverbs are attested without variation.
Reception History
In church history, the four night watches of Mark 13:35 have been read both literally and allegorically. Gill notes that some Christians understood the seasons as representing the several ages of men: childhood, youth, manhood, and old age, a way to apply the call to watchfulness to every stage of life. The image of the cockcrow also carried strong associations with Peter's denial and restoration (Mark 14:30), reminding hearers that alertness includes humility and dependence on grace. Throughout the medieval period, the night watches became a shorthand for the constant vigilance required of those awaiting the Bridegroom, echoed in monastic vigils and in hymns that urged believers to stay awake for the Lord's return.
Preaching This Verse
Three-point outline
- The Command to Watch, The imperative γρηγορεῖτε calls for sustained, active alertness. Vincent notes the picture of a sleeping man rousing himself. Watchfulness is not passive waiting but engaged readiness.
- The Reason for Watchfulness, “You don’t know when the master of the house is coming.” As Jesus says in verse 33, “you don’t know when the time is.” Uncertainty is not an excuse for inattention; it is the very reason to stay awake.
- The Four Watches of the Night, Evening, midnight, cockcrow, morning. These cover every watch of the night, reminding us that the Master may come at any hour. The Temple practice of a sudden knock underscores the surprise that faithful servants must be ready for.
Five-point outline
- Identity: Jesus is the Master of the house. He has given authority and work to each servant (verse 34).
- Command: Keep watch. The verb is present imperative, continue watching. This involves both vigilance against spiritual sleep and diligence in assigned tasks.
- Motivation: You do not know the hour. The absolute negative (οὐκ) underscores complete lack of knowledge regarding the timing of his return (verse 32).
- The Night Watches: Each watch (evening, midnight, cockcrow, morning) corresponds to a period of waiting. Historically, these were the times when the temple guards could be caught off guard. Spiritually, they represent the seasons of life or church history.
- The Warning: “Lest coming suddenly he find you sleeping” (verse 36). The consequence is not loss of salvation but loss of readiness and blessing. Revelation 16:15 echoes this: “Blessed is he that watcheth and keepeth his garments.”
Illustration hooks
- The night shift worker: A security guard on the graveyard shift knows that the supervisor may do a spot check at any time. He cannot afford to doze off, even if hours pass without incident. The Christian lives in a similar state of holy alertness.
- The Temple night watch: The captain of the temple would knock without warning. The guards had to be awake and dressed, ready to answer. This historical picture, grounded in the Mishnah, illustrates the suddenness of Christ’s return and the need for immediate readiness.
- The delayed flight: Passengers waiting for a long-delayed flight often let their guard down, they wander away, fall asleep, become distracted. When the gate change is finally announced, they scramble. Jesus’ warning is to stay near, stay awake, and be ready to board at a moment’s notice.
Questions your congregation is asking
- “What does watching look like on a Tuesday morning?” Does it mean constantly thinking about the end times, or does it show up in ordinary faithfulness, prayer, and obedience to the tasks God has given?
- “How do I stay alert when it feels like Jesus is taking a long time?” Generations have waited. The temptation to spiritual drowsiness grows with delay. How do we keep the flame of expectation alive without becoming anxious or obsessed?
- “Does this verse mean I should be afraid of Christ’s return?” The tone here is not terror but loving urgency. The same master who returns is the one who gave his servants work and authority (verse 34). Watching is preparation, not panic.
Leading a Discussion
Mark 13:35 calls us to a life of alertness. As you study this verse together, consider the difference between passive waiting and active watching. Let the unexpectedness of the master's return shape how you live this week.
Discussion questions
- What stands out to you about the command “Watch” in this verse? How does the context of the night watches affect your understanding?
- Why does Jesus repeatedly emphasize that we do not know the hour? How does uncertainty serve as a motivation rather than a frustration?
- The four watches cover the entire night. What does this suggest about the comprehensiveness of the watchfulness required?
- In the temple practice, the priest could knock at any moment. How does this image help you imagine readiness for Christ’s return?
- Read verse 36: “Lest coming suddenly he find you sleeping.” What forms can spiritual sleep take in your daily life?
- Verse 34 mentions that the master gave to each servant his work. How does staying busy with the work assigned to you relate to watching?
- What is one practical step you can take this week to be more alert to the Lord’s presence and return?

What the Commentators Say
8 public-domain commentaries, condensed into plain language.
Adam Clarke's Commentary Methodist/Wesleyan 1826
Clarke argues that the certainty of Christ's return should make readiness instinctive, not forced. He compares believers to a prisoner under a death sentence who needs no reminder to prepare, and to one expecting release who stays ready at every moment. Both fear and hope drive the same diligent watchfulness.
Barnes' Notes on the Bible Protestant 1832
Barnes defines "watch" as diligent, faithful waiting for the Lord's return at an unexpected hour. He identifies the master of the house as Jesus himself, and notes that the reference to evening, midnight, and other times comes from the four divisions into which the Jews divided the night.
Cambridge Bible for Schools and Colleges Anglican 1880
The Cambridge commentary draws a direct link between Jesus' warning and the Temple's night watch. The priest in charge of the Levitical guard would come suddenly and knock, and the Rabbis used the same language to describe the Master's unexpected coming. This shows the familiar religious context behind Jesus' parable.
Geneva Bible Notes Reformed 1599
The Geneva Notes draw attention to the four specific watches of the night listed here—evening, midnight, cockcrow, and dawn—to stress that Christ's return could come at any hour. Because the time is completely unknown, believers must remain constantly alert through every division of the night.
Gill's Exposition of the Bible Baptist 1748
Gill grounds the four night watches in the actual practice of the temple president's arrival, who came at varying times such as cock crowing or midnight. He notes that this division matches Jewish and Roman customs. Some apply these seasons to the ages of life, but Gill's focus is the historical setting.
Jamieson-Fausset-Brown Commentary Protestant 1871
JFB points out that the four time references in this verse correspond directly to the four Roman watches of the night. This detail grounds the call for vigilance in the actual nighttime guarding practices of the period, showing that readiness is demanded at every hour the watch changes.
Matthew Henry's Commentary Reformed/Presbyterian 1710
Henry reads the fig tree parable as a straightforward lesson about reading the signs of Jerusalem's coming destruction. Just as budding leaves promise summer, these events promised that the city's fall was near. The exact day remained hidden, so the only wise response was constant watchfulness and prayer.
Vincent's Word Studies Evangelical 1887
Vincent distinguishes two Greek words for watchfulness. The one used here pictures a sleeping person rousing himself, adding alertness to simple wakefulness. He illustrates this with temple guards who had to rise and salute the captain during night rounds, matching the imagery of a master who might knock at any moment.
