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 and therefore the cloth shall be burnt with flames of fire. (and so the cloak shall be burned in the fire.)

53 And if the priest seeth that the spot hath waxed not, (And if the priest seeth that the spot hath not grown, or not spread,)

54 he shall command, and they shall wash that thing wherein the leprosy is, and he shall close it again seven other days (and he shall enclose it for another seven days);

55 and when he seeth the former likeness not changed again, nevertheless that neither the leprosy hath waxed, he shall (still) deem that thing (to be) unclean, and he shall burn it in fire, for the leprosy is shed in the over-part of that cloth, either through[out] it all (for there is leprosy on the outer part of that cloak, or on the inside of it).

56 Else if the place of [the] leprosy is darker, after that the cloth is washed, he shall break away that dark place, and he shall part it from the whole. (But if the place of the leprosy is darker, after that the cloak is washed, he shall tear away that dark place, and so he shall part it from the whole.)
