Psalm 89:35 means that God has bound himself by an oath that he will not deceive or abandon the promise he made to David. Because God swore by his own holiness, the promise rests on his character rather than on David’s performance. The verse is spoken by the psalmist, Ethan the Ezrahite, who is praying to God in the middle of a crisis that seems to contradict everything God said he would do.
Once I have sworn by my holiness, I will not lie to David.

What Psalm 89:35 Means
The phrase “once I have sworn by my holiness” points to a solemn vow. In ancient Israel, an oath called on the most sacred reality available to back up a promise. Here God does not swear by anything greater than himself, so he swears by his own holiness, the perfect purity and faithfulness that define who he is. Nothing could be more binding.
“I will not lie to David” is a statement about trustworthiness. God is saying that he will not be a liar, a claim he makes for his own sake and for the sake of the king he chose. The verse does not promise that David’s descendants will never face trouble or that every circumstance will feel secure. It promises that God will keep his word about the line of David, even when the people of Israel are experiencing defeat and exile.
The Context of Psalm 89:35
Psalm 89 is a long hymn in the book of Psalms, a collection of Israel’s prayers and songs. The opening half celebrates God’s loyal love and the covenant he made with David, found in 2 Samuel 7. The psalm then turns sharply in verses 38 to 45, where the writer laments that the throne has been overturned and the anointed king humiliated. Psalm 89:35 sits right in the middle of that turn, so the reader is being reminded of God’s faithfulness at the very moment it looks most doubtful.
Read this way, the verse is not a naive assurance written from comfort. It is a truth held onto while the ground is shaking. The surrounding verses about God’s loving kindness and faithfulness not failing show that the writer is wrestling with apparent broken promises, and Psalm 89:35 is the anchor he returns to in that struggle.

Lord, you have sworn by your own holiness, and you do not lie. When my circumstances seem to contradict everything you have promised, help me remember who you are. Steady my heart when my questions grow loud and my understanding feels small. Teach me to lean on your faithfulness rather than on my fears, and to trust that you keep your word even when I cannot see how. Amen.
