What does Psalm 26:11 mean?

A person's "walk" refers his lifestyle. After pointing out the sinfulness of the hypocritical evildoers, David returns to his earlier affirmation of his integrity (Psalm 26:1–3). David's pursuit of holiness was not sporadic, nor was it temporary. Sincere devotion to God was the regular pattern of his life.

David also asks the Lord to redeem him. The meaning of "redeem" in this context is not a deliverance from sin but a deliverance from David's enemies. The word is often used in reference to Israel's deliverance from Egypt (Deuteronomy 7:8; 9:26; 13:5; 15:15; 24:18; 2 Samuel 7:23; Micah 6:4).

To be "gracious" is to be kind or to favor a person. The Lord is gracious to all His people, not because they deserve it, but because He loves them unconditionally. Because Jonah knew the Lord is gracious and would pardon the repentant, he initially refused the Lord's commission to preach in Nineveh (Jonah 4:2).
