Psalm 40:1-5

Unto the end. A Psalm of David himself. Blessed is he who shows understanding toward the needy and the poor. The Lord will deliver him in the evil day. May the Lord preserve him and give him life, and make him blessed upon the earth. And may he not hand him over to the will of his adversaries. May the Lord bring him help on his bed of sorrow. In his infirmity, you have changed his entire covering. I said, "O Lord, be merciful to me. Heal my soul, because I have sinned against you."
