One word frequently found in the book of Psalms is prayer. There are some people that never pray for various reasons. But one that I hear often is that they do not know what to say. Although it is not stated in the title of this Psalm, we could quickly describe it as an evening prayer. Sent up in the night before going to bed, instructing us to reflect upon our ways and the good we received from the Heavenly Father.
