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 it shall be burnt with fire.

53 But if he see that it is not grown,

54 He shall give orders, and they shall wash that part wherein the leprosy is: and he shall shut it up other seven days.

55 And when he shall see that the former colour is not returned, nor yet the leprosy spread, he shall judge it unclean: and shall burn it with fire, for the leprosy has taken hold of the outside of the garment, or through the whole.

56 But if the place of the leprosy be somewhat dark, after the garment is washed, he shall tear it off, and divide it from that which is sound.
