Luke New Testament Greek

Context

This verse is part of the Gospel of Luke's opening scene. Zechariah, an elderly priest from the tribe of Levi, is serving in the Jerusalem temple when the angel Gabriel appears to him. Gabriel announces that Zechariah and his wife Elizabeth will have a son named John, who will prepare the people for the Lord. After a lifetime of prayer, the moment has finally come. But Zechariah asks, “How can I be sure of this? For I am an old man, and my wife is well advanced in years.” The angel responds by giving him a sign of his own, silence, until the promise is fulfilled. This is both a gentle judgment for unbelief and a gracious confirmation that God's word will not fail.

Key Words

Three Greek words give the verse its texture. Σιωπῶν (siōpōn) describes a silence that continues, as Vincent notes: “you will be being silent.” It is not Zechariah choosing quiet, it is a stillness imposed on him, a space to listen instead of speak. Then οἵτινες (hostis) is a qualitative pronoun: Gabriel calls his words “the kind that shall be fulfilled.” The angel does not merely say these words will happen; he says they belong to a class of things that must come to pass. The final key is καιρὸν (kairon), the appointed season. Not just time passing, but the perfect moment God has determined. Zechariah's unbelief cannot alter that season. The promise will ripen exactly when God intends, and silence will give way to praise.

How Christians Read This Verse

Reformed commentators like Calvin see the punishment as fitting: Zechariah wanted a sign, so he got one, but one that silenced his murmuring and forced him to wait on God. The Geneva Bible calls it a “gentle chastisement.” Wesley notes the Greek word implies Zechariah was struck deaf as well as mute, since people later had to make signs to him. Catholic tradition has often read this as a temporary purification of Zechariah's faith, a mercy wrapped in discipline. Across traditions, the common thread is that God's word stands firm even when our faith falters. The same angel who rebukes him also promises that the child will bring joy to many, and that the silence will not last forever.

A common misunderstanding

Some think Zechariah was punished simply for asking a question, as if God forbids honest inquiry. In fact, the angel had just finished speaking a clear promise from God's own presence, Zechariah did not ask for clarification; he expressed unbelief disguised as a request for proof. His question, “How can I be sure?” contradicted the word of the angel who stands before the throne of God. This is different from Gideon, who humbly asked for a sign to confirm a calling. Zechariah had the sure word, and he still refused to trust it.

Living This Out

This week, you may find yourself holding a promise from God that seems too good to be true. Maybe it is a Scripture you have prayed for years, or a quiet assurance that God is at work in a situation that looks hopeless. It is easy to start arguing with the promise, listing reasons it cannot happen. The hard and holy work is to stop talking and start trusting. Sometimes God answers our doubt by closing our mouths so we can learn to listen. The silence is not the end. The season will come when the promise is fulfilled, and you will speak again, this time with praise.

Main takeaway: God's promises will be fulfilled at their appointed time, whether we believe them or not; unbelief only silences our praise, not God's plan.

For Families

For ages 5, 8

Zechariah didn't believe God's promise, so God made him quiet for a long time. But God still kept His promise and gave him a son named John.

For ages 9, 12

Zechariah had been praying for a child his whole life. When God finally said yes, Zechariah found it hard to believe. So God gave him a sign that was also a time to trust without talking. Sometimes when we doubt, God lets us be quiet until we see He keeps His word. That silence can be hard, but it teaches us to rely on God's timing, not our own.

Questions People Ask

Why did God make Zechariah mute instead of just rebuking him?

The silence served two purposes at once: it was a gentle punishment for Zechariah's unbelief, and it was also the very sign he had asked for. Zechariah wanted proof that the promise was real, and he got it, in a way that forced him to stop arguing and simply wait. Nine months of quiet taught him to trust God's timing. The fact that the silence ended exactly when the child was born proved that Gabriel had spoken the truth.

Was Zechariah deaf as well as mute?

Many early commentators think so. John Wesley points out that when Zechariah came out of the temple, people had to make signs to communicate with him (Luke 1:62). If he could hear, they would not have needed gestures. The Greek word used in verse 20, σιωπῶν, normally means silent, but the behavior of the crowd strongly suggests his hearing was also affected. Both the silence and the deafness were signs that God had visited the temple that day.

How is Zechariah's request for a sign different from Gideon's request in Judges?

Gideon asked for a sign after being called to lead Israel against a vast army, and his request came from a place of humility and weakness. He was not arguing with God's promise; he was seeking confirmation of his own role. Zechariah, by contrast, had just received the angel Gabriel's direct announcement in the most holy place of the temple. His question, “How can I be sure of this?” questioned the trustworthiness of God's word itself. That is why the response was different.

Did Zechariah ever speak again?

Yes, at the circumcision of John eight days after the birth, Zechariah wrote the baby's name on a tablet, and immediately his mouth was opened and his tongue freed (Luke 1:64). His first words after nine months of silence were praise and thanksgiving. The punishment had a clear ending point, the fulfillment of the promise. This shows that God's discipline is not meant to crush but to restore, and it always gives way to joy when we see His faithfulness.

Why does this verse matter for readers today?

Many of us find ourselves in Zechariah's position: we have prayed for something for so long that when God finally says yes, we cannot quite believe it. This verse reminds us that God's promises do not depend on the strength of our faith. Even when we doubt, His plan moves forward. The silence we experience may be God's way of teaching us to wait trustfully. In the end, He fulfills His word, and we get a story of His faithfulness to tell.
