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 The priest must burn the clothing. It does not matter if it is woven or knitted, wool or linen, or made of leather, because the mildew is spreading. It must be burned.

53 "If the priest sees that the mildew has not spread in the cloth (either knitted or woven) or leather,

54 he must order the people to wash that piece of leather or cloth. Then he must separate the clothing for seven more days.

55 After the piece with the mildew has been washed, the priest must look at it again. If the mildew still looks the same, the piece is unclean, even if the mildew has not spread. You must burn it in fire; it does not matter if the mildew is on one side or the other.

56 "But when the priest looks at that piece of leather or cloth, the mildew might have faded after the piece has been washed. Then the priest must tear the mildew out of the piece of leather or cloth (either woven or knitted).
