This may have been written at the same time as the two previous psalms. Again, David mentions that his spirit is overwhelmed, and his only recourse was to remember, meditate and consequently stretch forth his hands to God. There was a soul-thirst that only God could meet.
His urgency is especially noted by his supplications in vv. 7-11, hear me; cause me; deliver me; hide me; teach me; lead me and quicken me. When trouble becomes personal, then one’s prayer gets very personal. The grounds of David’s prayer rested not in any qualification in himself, but even though he be king, he saw that he was but the Lord’s servant: a role of submission and service. So also our Lord was God’s servant, whom He upheld, and His elect in whom He delighted.
