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 in which is the plague, whether warp or woof, in wool or in linen, or anything of leather, for it is an active leprosy; the garment shall be burned in the fire.

53 "But if the priest examines it, and indeed the plague has not spread in the garment, either in the warp or in the woof, or in anything made of leather,

54 then the priest shall command that they wash the thing in which is the plague; and he shall isolate it another seven days.

55 Then the priest shall examine the plague after it has been washed; and indeed if the plague has not changed its color, though the plague has not spread, it is unclean, and you shall burn it in the fire; it continues eating away, whether the damage is outside or inside.

56 If the priest examines it, and indeed the plague has faded after washing it, then he shall tear it out of the garment, whether out of the warp or out of the woof, or out of the leather.
