Have mercy. Heartbroken from a consciousness of his great sin against Uriah and Bath-sheba, crushed under the weight of guilt, David cries to God for mercy. There is in this cry no excuse, no apology, no attempt to vindicate, no complaint against the justice of the law that condemned him. In true humility David blames no one but himself.
Lovingkindness. See Additional Note on Ps. 36. When we have no sense of sin, we talk of justice; when we sense the need of a Saviour, we talk of love.
Multitude. In the vastness of God’s mercy David could safely trust.
Blot out. Erase from the book in which the record of man’s actions is kept (see Ex. 32:32, 33; Isa. 43:25; 44:22; Acts 3:19).
