Scripture Reading: â€œPurge me with hyssop, and I shall be cleanâ€¦â€ (Psalm 51:7)
David knew that it would take the strongest of cleansers to purge him of his sins. Thus, he pleaded for God to â€œpurge [him] with hyssop.â€
Hyssop was used to apply the blood of the Passover lambs to the doorposts of the Hebrewsâ€™ homes in Egypt (Exodus 12:22). As a result, the judgment of God on Egypt passed over the homes of the Hebrews. David understood how he, like the enslaved Jews in Egypt, needed Godâ€™s judgment on sin to passover him.
Hyssop was also used in the cleansing of lepers (Leviticus 14:1-7). Like a leper, David was incurably corrupt and the victim of a fatal infirmity. Nothing apart from Godâ€™s miraculous intervention could cleanse him from his sinful corruption and spare him from sinâ€™s inevitable consequence; namely, death (Romans 6:23).
It is no coincidence that hyssop was used to put the sponge of sour wine to Christâ€™s mouth before He cried from the cross, â€œIt is finishedâ€ (John 19:28-30). As the Bible clearly teaches, there is no cleansing of sin apart from the shedding of blood (Hebrews 9:22). It is the blood that Christ shed on the cross alone that can purge the sinner from his sin and cleanse him from sinâ€™s corruption.
â€œWhat can wash away my sin?
Nothing but the blood of Jesus;
What can make me whole again?
Nothing but the blood of Jesus.
Oh! precious is the flow
That makes me white as snow;
No other fount I know,
Nothing but the blood of Jesus.â€ (Robert Lowry)
