Vayikra 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.

Vayikra 13:54 In-Context

52 He shall therefore burn that garment, whether warp or woof, in wool or in linen, or any thing of leather, wherein the nega is; for it is a malignant tzara’at; it shall be burned in the eish.

53 And if the kohen shall examine, and, hinei, the nega be not spread in the garment, either in the warp, or in the woof, or in anything of leather,

54 Then the kohen shall command that they wash the thing wherein the nega is, and he shall quarantine it another shivat yamim;

55 And the kohen shall examine the nega, after that it is washed; and, hinei, if the nega has not changed its appearance, and the nega be not spread, it is tamei; thou shalt burn it in the eish; whether the eating away hath brought bareness in the front or back.

56 And if the kohen examine, and, hinei, the nega be somewhat faded after the washing of it, then he shall tear it out of the garment, or out of the leather, or out of the warp, or out of the woof;
