David begins by asking God for mercy, because man tramples on him, and all day long an attacker oppresses him. His enemies trample him all day, for many attack him proudly. Then he confesses his fear and his decision: when I am afraid, I put my trust in you. In God, whose word I praise, in God I trust; I shall not be afraid. What can flesh do to me?
Next he describes his adversaries: all day long they injure my cause; all their thoughts are against me for evil. They stir up strife, they lurk, they watch my steps as they have waited for my life. David asks God to cast them down in wrath. Then he says something very personal: you have kept count of my tossings; put my tears in your bottle. Are they not in your book? Then my enemies will turn back in the day when I call. This I know, that God is for me.
The refrain returns: in God, whose word I praise, in the Lord, whose word I praise, in God I trust; I shall not be afraid. What can man do to me? The psalm ends with a commitment: I must perform my vows to you, O God; I will render thank offerings to you. For you have delivered my soul from death, yes, my feet from falling, that I may walk before God in the light of life.
