Pues aun no está la palabra en mi lengua, y he aquí, oh Jehová, tú la sabes toda.
Mesmo não havendo ainda palavra alguma em minha língua, eis, SENHOR, que já sabes tudo.
Car la parole n’ est pas sur ma langue,
Denn siehe, es ist kein Wort auf meiner Zunge, das du, HERR, nicht alles wissest.
Als er nog geen woord op mijn tong is, zie, HEERE! Gij weet het alles.
Poiché la parola non è ancora sulla mia lingua, che tu, o Eterno, già la conosci appieno.
Nim przyjdzie słowo na język mój, oto Panie! ty to wszystko wiesz.
изощряют язык свой, как змея; яд аспида под устами их.
耶和華啊， 我舌頭上 的話，你沒有一句 不知道的。
For there is not a word on my tongue which is not clear to you, O Lord.

Scholars' Consensus
Commentators across traditions agree that this verse asserts God's complete knowledge of every word, even before it is uttered. Adam Clarke emphasises that God knows our words before they are shaped on the tongue. Barnes adds that God knows both what is said and what is meant, the sincerity or hypocrisy behind it. The Cambridge Bible argues that God knows not merely the spoken word but the secret thoughts that prompt it. Gill, citing the Targum, says God knows the word before it is formed in the mind. Thus the consensus is clear: God's knowledge of our speech is total, reaching into the unspoken intention and the moment before articulation.

What Scholars Agree and Debate
| Topic | Agreed | Debated |
|---|---|---|
| Timing of God's knowledge of our words | God knows our words completely, their content, meaning, and intent. | Some traditions read the verse as describing God's knowledge of words already spoken; others (following Gill, Clarke, Cambridge Bible) stress that God knows them even before they are formed on the tongue. |
| Relationship of God's knowledge to human freedom | God's foreknowledge does not negate human responsibility for speech. | Christians differ on whether God's knowledge includes all possible words we might speak (Arminian emphasis on conditional foreknowledge) or only what we actually will speak (Reformed emphasis on exhaustive foreordination). |
| Implications for prayer | God hears both vocal and silent prayers, and knows the heart's desire before it is expressed. | Some traditions stress the importance of verbal articulation in prayer as a discipline; others highlight that God already knows and responds to unspoken needs. |
Historical & Cultural Context
Psalm 139 is a Davidic psalm that explores God's omniscience, omnipresence, and intimate involvement in human life. The superscription attributes it to David, though some commentators (noted by Keil & Delitzsch) observe Aramaic forms that may suggest a later period; still, the majority view accepts Davidic authorship. The psalm begins with a declaration of being searched and known (v.1), then moves through specific domains: actions (v.2), thoughts (v.3), words (v.4), and location (vv.7, 12). Verse 4 stands at the centre of the first strophe, shifting from God's general awareness to His knowledge of speech. The Hebrew verb yada‛ (יָדַע) carries the sense of intimate, experiential knowing, not mere factual awareness. The word mil lah (מִלָּה) for “word” is used elsewhere in Job for speech or utterance. The structure of the verse, with the introductory ki (“for”) and the emphatic hen (“behold”), creates a tone of awe and confession. Ancient Near Eastern cultures often believed that only human beings could hear spoken words; the psalm boldly claims that God already knows them before they are voiced.
Textual Notes
The supplied sources note no significant textual variants for Psalm 139:4. The Masoretic Text is stable, and the verse reads consistently across manuscripts. The only minor variation appears in the vocalisation of the Hebrew word kullah (all of it), which is uniformly rendered in the versions.
Reception History
Psalm 139 has been treasured across Jewish and Christian traditions for its sublime portrait of God's intimate knowledge. Verse 4, in particular, has been cited in discussions of divine omniscience and the nature of prayer. Early Christian writers such as Augustine referenced the psalm to show that God knows the heart better than we do. In medieval monasticism, the verse was used as a prompt for self-examination before confession. Theologians from Calvin to Wesley have drawn on it to argue that God's knowledge extends to every intention. In modern hymnody, the psalm has been set to music as a declaration of trust. The verse remains a source of comfort for believers who feel their words are clumsy or insufficient, reminding them that God already understands what they struggle to express.
Preaching This Verse
Three-point outline
- God hears every word we speak. Nothing mumbled, whispered, or shouted escapes His notice.
- God knows the words we are about to speak. Before they reach our tongue, He already understands their content and intent.

- How can I live authentically when I know God sees through every word?
Leading a Discussion
Psalm 139:4 pulls back the curtain on God’s knowledge of our speech. David marvels that before a word even forms on his tongue, God knows it completely. This truth can feel both unsettling and comforting. As you discuss, let the group move from what the text says to what it means for everyday life.
Discussion questions
- Read Psalm 139:1, 4. What pattern do you notice in how David describes God’s knowledge: actions, thoughts, words?
- The Hebrew word yada‛ means more than head-knowledge; it points to intimate, relational knowing. How does that shape your understanding of this verse?
- David says God knows the word before it is on his tongue. What does that imply about God’s relationship with time and our thoughts?
- Why do you think David moves from “you have searched me” to “you know it altogether”? What emotional progression do you see?
- How does knowing God hears even unspoken words affect the way you pray? Is there a difference between silent and spoken prayer in your experience?
- This verse can feel threatening, God knows every careless word. How can it also be a source of comfort?
- What one change might you make in your speech this week if you truly believed God already knows what you are about to say?

What the Commentators Say
6 public-domain commentaries, condensed into plain language.
Adam Clarke's Commentary Methodist/Wesleyan 1826
Clarke draws attention to the Hebrew word ki in the original, which he reads as meaning "although." Even when no word has yet formed on the tongue, God already knows the whole of it, just as He knows thoughts that are not yet shaped.
Barnes' Notes on the Bible Protestant 1832
Barnes draws a sharp distinction between what we say and what we actually mean. Mere hearing words does not give full knowledge, since speech can be false or insincere. God, however, knows the spoken word and the hidden intent behind it without any gap.
Calvin's Commentaries Reformed 1564
Calvin argues that David wrote this psalm to strip away every excuse and pretense, forcing the reader to face the fact that nothing is hidden from God. The proof lies in our very creation: the One who formed every part of us in the womb cannot possibly be ignorant of how we live.
Geneva Bible Notes Reformed 1599
For there is not a word in my tongue, but loe, thou knowest it wholy, O Lord.
Gill's Exposition of the Bible Baptist 1748
Gill draws attention to the moment before a word is spoken. He notes that God knows not only what will be said but the entire thought, intention, and purpose behind it, even while the word is still unformed in the mind. This includes the prayers and private conversations of believers.
Matthew Henry's Commentary Reformed/Presbyterian 1710
For Henry, David's point is that God's perfect knowledge is not a doctrine merely to be preached but a truth to be prayed. He makes it intensely personal: not "Thou knowest all" but "Thou knowest me," acknowledging that his own heart, thoughts, and ways are fully open before the Lord.
