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 shall therefore burn that garment, whether warp or woof, in woolen or in linen, or anything of skin, in which the plague is; for it is a fretting leprosy; it shall be burnt in the fire.

53 And if the priest shall look and it appears that the plague has not spread in the garment, either in the warp, or in the woof, or in anything of skin,

54 then the priest shall command that they wash the thing in which the plague is, and he shall shut it up again for seven days.

55 And the priest shall look on it after the plague has been washed; and if it appears that the plague has not changed its colour, even if the plague is not spread, it is unclean; thou shalt burn it in the fire; it is fret inward, whether the bare spot is within or without.

56 And if the priest looks and the plague appears to be darker after the washing of it, then he shall cut it out of the garment or out of the skin or out of the warp or out of the woof.
