Psalm 37, of David. With two lines dedicated to each letter of the Hebrew alphabet, this psalm is one of the longer acrostics in the book of Psalms. David wrote it late in life (“ I have been young, and now am old;
Yet I have not seen the righteous forsaken,
Nor his descendants begging bread.“) It is full of promises and praise and was intended for memorization.
Psalm 38, of David, a Petition. This is a Psalm of deep despair and remorse. David acknowledged his sin and cried out to God. Yet, in failing health and abandoned by friends and family, his hope in God remained steadfast.
