Psalm 17:10 describes the hardened heart and the boastful speech of people who are opposed to the psalmist. The verse is a complaint, not a promise. David, the traditional author of this prayer, is speaking to God about enemies who have closed themselves off to mercy and who talk with arrogance while they pursue him.
They close up their callous hearts. With their mouth they speak proudly.

What Psalm 17:10 Means
The phrase “close up their callous hearts” pictures a heart that has been shut like a door or wrapped in fat, unable to feel pity or to respond to conscience. The writer is not describing a passing bad mood. He is describing a settled posture of hardness toward others, the kind that stops listening to correction and stops noticing the suffering it causes.
“With their mouth they speak proudly” shows how that inner hardness comes out in speech. Their words are full of self-importance and contempt, and they seem to delight in saying what they please without restraint. The verse does not promise that God will instantly fix these people or that the psalmist will be spared all hardship. It names the reality of arrogant opposition and then carries that reality into prayer.
The Context of Psalm 17:10
Psalm 17 is a prayer for help from someone who believes he is innocent and is being hunted. The psalmist asks God to hear his plea, to examine his heart, and to protect him as the “apple of your eye.” Verse 10 is part of his description of the enemies who surround him, which runs through verses 9 to 12 and builds toward his cry in verse 13 for God to rise up and confront them.
Seeing that setting changes how the verse reads. The hard hearts and proud words are not an abstract complaint about human nature. They are the specific threat the psalmist faces, and his response is to bring that threat directly before God rather than trying to answer it with his own force.

This verse shows the same pattern of hurt and trust. The psalmist feels surrounded by opposition yet chooses to rest in God’s steadfast love, which helps explain how a prayer can be both a complaint and an act of faith.
Psalm 64:3-4
3 Who sharpen their tongue like a sword, and aim their arrows, deadly words, 4 to shoot innocent men from ambushes. They shoot at him suddenly and fearlessly.

These verses describe enemies who sharpen their tongues like swords, echoing the proud speech of Psalm 17:10. They also show the psalmist asking God to hide him from such plots, which parallels the request for shelter in Psalm 17.
A Short Prayer From Psalm 17:10
Lord, you see the hardness in some hearts and hear the proud words that wound me. I do not pretend those things are small. I bring them to you and ask you to look at what is happening and to act with justice. Keep my own heart soft toward you, even when others close theirs. Hide me under the shadow of your care, and give me the patience to wait for your help rather than answering arrogance with arrogance. Amen.
