What Is Hyssop?
Hyssop is an evergreen plant that originally grew in southern Europe, the Middle East and central Asia. It’s classified as a garden herb, and is part of the mint family.
Hyssop  is mentioned several times in the Old and New Testaments of the Bible in relation to the process of being cleansed.
 
What Hyssop Symbolizes in the Bible
The hyssop plant symbolizes the chance God offers us to be washed clean of sin. It’s also a reminder that He uses everything, including our mistakes, for our good
 
“Wash away all my iniquity and cleanse me from my sin” (Psalm 51:2). “Create in me a pure heart, O God, and renew a steadfast spirit within me” (Psalm 51:10).
 
Exodus 12 during the Passover. The Israelites were instructed to take a bunch of hyssop and dip it in the blood of a lamb, then smear the blood on the doorposts of their homes as a sign for the Lord to "pass over" them during the plague of the firstborn. 
 
This act of using hyssop to apply the sacrificial blood emphasizes the plant’s association with purification and protection, symbolizing the deliverance of God’s chosen people.
 
Psalm 51:7 - “Cleanse me with hyssop, and I will be clean; wash me, and I will be whiter than snow.” David wrote Psalm 51 after he committed adultery with Bathsheba and had her husband killed. The prophet Nathan convicted David of sinning against the Lord, and this passage was part of his heartfelt response. Hyssop is mentioned in connection to the renewal process that David seeks.
 
In the New Testament, hyssop was an instrument of comfort for Jesus as he hung on the cross and shed His blood to cleanse us of our sin.
 
John 19:29-30 - “A jar of wine vinegar was there, so they soaked a sponge in it, put the sponge on a stalk of the hyssop plant, and lifted it to Jesus’ lips. When he had received the drink, Jesus said, ‘It is finished.’ With that, he bowed his head and gave up his spirit.”
 
The hyssop plant symbolizes the chance God offers us to be washed clean of sin. It’s also a reminder that He uses everything, including our missteps and mistakes, for our good.
 
 
A reminder of Jesus Christ.
We are by nature sinful; we cannot fix ourselves. But David’s words show us we don’t have to stay stuck in that place. If we admit our need for God’s touch and humbly ask Him to forgive us, He will bring a deep cleansing.
 
Hebrews 9:13-14 - "Jesus  through the eternal Spirit offered himself unblemished to God, cleanse our consciences from acts that lead to death, so that we may serve the living God!" This process of being purified will result in a more vibrant worship life. Like David, we’ll find ourselves lifting up praise and worship, giving testimony, and helping others know God more fully. And our sense of gratitude and joy will grow.
