Λευιτικόν 14:13

Verse 13. But preparation for this worship from the truth of innocence is by the removal of evil, and the reception of celestial good internally, yea, even in the inmost degree of the mind; for as the removal of actual evil is from the Lord in this way, even so it is with evil committed in a state of the innocence of ignorance; worship with a view to its removal is essentially holy.
