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, weave, or knit, whether the contaminated item is wool or linen or leather. Since the mildew is harmful, the article must be burned up.

53 But when the priest reexamines it, if the mildew has not spread in the fabric, weave, knit, or leather article,

54 the priest is to order the contaminated article to be washed and isolated for another seven days.

55 After it has been washed, the priest is to reexamine it, and if the mildewed article has not changed in appearance, it is unclean. Even though the mildew has not spread, you must burn it, whether the rot is on the front or back.

56 If the priest examines it and the mildew has faded after it has been washed, he must cut the contaminated section out of the fabric, leather, weave, or knit.
