In God have I put my trust - The sentiment in this verse is the same as in Psalms 56:6, except that the word “man” is used here instead of “flesh.” The meaning, however, is the same. The idea is, that he would not be afraid of what “any man” - any human being - could do to him, if God was his friend.
