Leviticus 13:54 Meaning and Commentary

Leviticus 13:54

Then the priest shall command that they wash [the thing]
wherein the plague [is]
The priest did not wash it himself, but ordered others to do it; and this was either the part in which the plague was, or the whole garment or skin in which it was; which may be typical of the washing of the garments of men in the blood of Christ, which cleanses from all sin, ( Revelation 7:14 ) ( 1 John 1:7 ) ( Zechariah 13:1 ) : and he shall shut it up seven days more:
the garment or skin in which the leprosy was, or suspected to be, to see what alteration would be made by that time through the washing, whether the colour would be altered, or whether it would spread any more or not.

Leviticus 13:54 In-Context

52 He is to burn the fabric, the warp or woof in wool or linen, or any leather article, which is contaminated. Since it is harmful mildew it must be burned up.
53 "When the priest examines [it], if the contamination has not spread in the fabric, the warp or woof, or any leather article,
54 the priest is to order whatever is contaminated to be washed and quarantined for another seven days.
55 After it has been washed, the priest is to reexamine the contamination. If the appearance of the contaminated article has not changed, it is unclean. Even though the contamination has not spread, you must burn up the fabric. It is a fungus on the front or back [of the fabric].
56 "If the priest examines [it], and the contamination has faded after it has been washed, he must cut the contaminated section out of the fabric, the leather, or the warp or woof.
