7 Purge me with hyssop, and I shall be clean; wash me, and I shall be whiter than snow. 8 Fill me with joy and gladness; let the bones which thou hast broken rejoice. 9 Hide thy face from my sins, and blot out all my iniquities. 10 Create in me a clean heart, O God, and put a new and right spirit within me. 11 Cast me not away from thy presence, and take not thy holy Spirit from me. 12 Restore to me the joy of thy salvation, and uphold me with a willing spirit. 13 Then I will teach transgressors thy ways, and sinners will return to thee.

14 Deliver me from bloodguiltiness, O God, thou God of my salvation, and my tongue will sing aloud of thy deliverance. 15 O Lord, open thou my lips, and my mouth shall show forth 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?
