7 Purge me with hyssop, and I shall be clean; wash me, and I shall be whiter than snow. 8 Make me to hear gladness and joy; [that] the bones which thou hast broken may rejoice. 9 Hide thy face from my sins, and blot out all mine iniquities. 10 Create in me a clean heart, O God, and renew a steadfast spirit within me. 11 Cast me not away from thy presence, and take not the spirit of thy holiness from me. 12 Restore unto me the joy of thy salvation, and let a willing spirit sustain me. 13 I will teach transgressors thy ways, and sinners shall return unto thee.

14 Deliver me from blood-guiltiness, O God, thou God of my salvation: my tongue shall sing aloud of thy righteousness. 15 Lord, open my lips, and my mouth shall declare thy praise.

Matthew Henry's Commentary on Psalm 51:7-15

Commentary on Psalm 51:7-15

(Read Psalm 51:7-15)

Purge me with hyssop, with the blood of Christ applied to my soul by a lively faith, as the water of purification was sprinkled with a bunch of hyssop. The blood of Christ is called the blood of sprinkling, Galatians 5:1. It is the Spirit of adoption spoken to the heart. Those to whom God is the God of salvation, he will deliver from guilt; for the salvation he is the God of, is salvation from sin. We may therefore plead with him, Lord, thou art the God of my salvation, therefore deliver me from the dominion of sin. And when the lips are opened, what should they speak but the praises of God for his forgiving mercy?
