Behold the humble hyssop plant,
A root that sprang from desert ground
That grew where other foliage can't,
Was where the cleansing blood was found.
Instructions from the great I AM
Regarding hyssop specified
That blood from the Passover lamb
Upon the doors must be applied.
The leper's cleansing ritual
And waters that would purify,
Employing hyssop's humble role,
Foreshadowed Christ who came to die.
The history of the hyssop, Lord,
To David's heart had been revealed,
As he cried out to be restored
And by Your cleansing blood was healed.
