7 Make me free from sin with hyssop: let me be washed whiter than snow. 8 Make me full of joy and rapture; so that the bones which have been broken may be glad. 9 Let your face be turned from my wrongdoing, and take away all my sins. 10 Make a clean heart in me, O God; give me a right spirit again. 11 Do not put me away from before you, or take your holy spirit from me. 12 Give me back the joy of your salvation; let a free spirit be my support. 13 Then will I make your ways clear to wrongdoers; and sinners will be turned to you.
14 Be my saviour from violent death, O God, the God of my salvation; and my tongue will give praise to your righteousness.
Matthew Henry's Commentary on Psalm 51:7-14
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?
