Hyssop was used during the first Passover in Exodus 12:22 — “Strike the lintel and the two side posts.” This would have bruised the hyssop leaves as they struck their doors and released the scent of oil to protect them from the death coming.
Psalm 51:7 states, “Cleanse me with hyssop, and I will be clean; wash me, and I will be whiter than snow.”
King David had an affair, got the woman pregnant, and then killed her husband, but he wasn’t repentant until the prophet Nathan confronted him. Suddenly he snapped out of it, saw his sin with clarity, and called for hyssop to cleanse him of his deep sin.
Historically, hyssop has been thought to be spiritually purifying and aid in cleansing oneself from sin, immorality, evil thoughts, or bad habits. Hyssop was also part of the leprosy recipe we talked about earlier along with cedarwood.
There is scientific basis for this:
Contains 50% ketones, which act like phenols and cleanse receptor sites.
Contains 5-10% sesquiterpenes that have been shown to delete addictions at the cellular level and help with compulsive behavior.
Contains 20-30% monoterpenes, which reprogram DNA and can restore normal function.
Known for its purifying properties, hyssop has a high ORAC value (antioxidant value).
In John 19:29, Hyssop was mixed with sour wine and offered to Jesus on the cross. Crucifixion, more than anything else, was a slow death by suffocation, and hyssop is supportive of the respiratory system. It was offered to ease His suffering.
