Matthew Henry Commentary Leviticus 14:54-57

"This is the law for all manner of plague of leprosy, and for a scall, and for the leprosy of a garment, and for a house, and for a rising, and for a scab, and for a bright spot; to teach when it is unclean, and when it is clean: this is the law of leprosy." — Leviticus 14:54-57 (ASV)

When God who is rich in mercy, for his great love with which he loved us, even when we were dead in sins, has quickened us by his grace (Ephesians 2:4–5), we will manifest the change by repenting, and forsaking former sins. Let us follow after holiness, and let us have compassion on other poor lepers, and desire, seek, and pray for their cleansing.
