8 Oh, give me back my joy again; you have broken me- now let me rejoice. 9 Don't keep looking at my sins. Remove the stain of my guilt. 10 Create in me a clean heart, O God. Renew a loyal spirit within me. 11 Do not banish me from your presence, and don't take your Holy Spirit from me. 12 Restore to me the joy of your salvation, and make me willing to obey you. 13 Then I will teach your ways to rebels, and they will return to you.

14 Forgive me for shedding blood, O God who saves; then I will joyfully sing of your forgiveness. 15 Unseal my lips, O Lord, that my mouth may praise you.

Matthew Henry's Commentary on Psalm 51:8-15

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?
