Psalms 51:1

1 To victory, the psalm of David; when Nathan the prophet came to him, when he entered to Bathsheba. God, have thou mercy on me; by thy great mercy. And by the muchliness of thy merciful doings; do thou away my wickedness. (To victory, the song of David, when Nathan the prophet came to him, after he had slept with Bathsheba. God, have thou mercy on me; because of thy great love. And in the multitude of thy merciful doings; do thou away my wickedness.)

Psalms 51:1 Meaning and Commentary

Psalms 51:1

Have mercy upon me, O God
David, under a sense of sin, does not run away from God, but applies unto him, and casts himself at his feet, and upon his mercy; which shows the view he had of his miserable condition, and that he saw there was mercy in God, which gave him hope; and upon his bended knees, and in the exercise of faith, he asks for it;

according to thy lovingkindness;
not according to his merits, nor according to the general mercy of God, which carnal men rely upon; but according to his everlasting and unchangeable love in Christ; from which as the source, and through whom as the medium, special mercy comes to the children of men. The acts of special mercy are according to the sovereign will of God: he is not moved to mercy neither by the merits nor misery of men, but by his free grace and favour; it is love that sets mercy to work: this is a most glaring gleam of Gospel light, which none of the inspired writers besides, except the Apostle Paul, saw, ( Ephesians 2:4 ) ( Titus 3:4 Titus 3:5 ) ;

according unto the multitude of thy tender mercies blot out my
transgressions;
for his sin was complicated, attended with many others; and, besides, upon a view of this, he was led to observe all his other sins; and particularly the corruption of his nature, his original sin, which he mentions, ( Psalms 51:5 ) . These he desires might be "blotted out"; out of the book of account, out of God's debt book; that they might not stand against him, being debts he was not able to pay or make satisfaction for; and out of the table of his own heart and conscience, where they were ever before him, and seemed to be engraven; that they might be caused to pass from him, and he might have no more conscience of them; or that they might be blotted out, as a cloud by the clear shining of the sun of righteousness, with the healing of pardoning grace in his wings; or that they might be wiped away, as any faith is wiped from any person or thing: and all this "according to the multitude of [his] tender mercies". The mercy of God is plenteous and abundant; he is rich in it, and various are the instances of it; and it is exceeding tender, like that of a father to his children, or like that of a mother to the son of her womb; and from this abundant and tender mercy springs the forgiveness of sin, ( Luke 1:77 Luke 1:78 ) . The psalmist makes mention of the multitude of the mercies of God, because of the multitude of his sins, which required a multitude of mercy to forgive, and to encourage his hope of it.

Psalms 51:1 In-Context

1 To victory, the psalm of David; when Nathan the prophet came to him, when he entered to Bathsheba. God, have thou mercy on me; by thy great mercy. And by the muchliness of thy merciful doings; do thou away my wickedness. (To victory, the song of David, when Nathan the prophet came to him, after he had slept with Bathsheba. God, have thou mercy on me; because of thy great love. And in the multitude of thy merciful doings; do thou away my wickedness.)

2 Moreover wash thou me from my wickedness; and cleanse thou me from my sin.

3 For I acknowledge my wickedness; and my sin is ever[more] against me. (For I confess my sinfulness; yea, my sin is before me forevermore.)

4 I have sinned to thee alone, and I have done evil before thee; that thou be justified in thy words, and overcome when thou art deemed. (I have sinned against thee alone, and I have done evil before thee; so that thou art justified with thy words, and proved right when thou judgest me.)

5 For lo! I was conceived in wickednesses; and my mother conceived me in sins. (For lo! I was conceived in sinfulness; yea, my mother conceived me in sin.)
