Psalm 17:10 describes enemies whose hearts have become closed and cold, and whose speech is arrogant and proud. David is describing the men who are persecuting him, and he is crying out to God for protection. The verse is part of a prayer, so it is not a general statement about all people but a specific complaint spoken to the Lord by someone under attack.
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 shut itself off. A callous is hardened skin built up from repeated pressure, so the image is of a heart that has grown thick and unfeeling, unable to show mercy or receive correction. The writer is not describing a passing bad mood but a settled hardness that has become part of who these people are.
The second line, “with their mouth they speak proudly,” shows where that hardness comes out. Their words are arrogant, boastful, and dismissive of others. The verse does not promise that these enemies will change or that David will be spared every harm. It names the problem honestly and leaves the outcome in God’s hands, which is what the rest of the psalm asks God to act on.
The Context of Psalm 17:10
Psalm 17 is traditionally attributed to David and is a prayer for justice from someone who feels wrongly hunted. The psalm is written from the perspective of a man who claims he has kept his way and wants God to see it. Verses 7 through 13 form a single appeal: David asks for God’s loving kindness, asks to be hidden under God’s protection, and then describes the enemies who surround him before calling on God to rise up and deliver him.
Read in that flow, Psalm 17:10 is the evidence David offers for why he needs rescue. Just before it he describes the wicked who oppress him, and just after it he says they are closing in on his steps like a predator. The verse therefore reads less as a general judgment on sinners and more as a plea that God would see the real danger David is in.

Psalm 95:8
Don’t harden your heart, as at Meribah, as in the day of Massah in the wilderness…

This verse warns against hardening the heart, using the same basic image of an unresponsive heart. Read alongside Psalm 17:10, it shows that a hard heart is a recurring concern in the psalms and a condition to be guarded against in our own lives.
A Short Prayer From Psalm 17:10
Lord, you see the hardness in the hearts of those who oppose me, and you see the pride in the words that wound me. I bring my pain to you and ask you to protect me from the harm they intend. Keep me under the shadow of your wings, and let me not become like them in my speech or my attitudes. Soften what needs softening in me, and give me the courage to speak truthfully and gently. I trust you to act with justice, because you are faithful even when people are not. Amen.
