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 will burn the clothing, the weaving of the wool or linen, or whatever skin item in which the infection was found, because it is an infectious skin disease; it must be burned with fire.

53 But if the priest sees that the infection has not spread in the clothing, the weaving, or on any skin item,

54 the priest will order that the infected piece be washed, and he will quarantine it for another seven days.

55 After it has been washed, if the priest sees that the infection has not changed its appearance, even though the infection has not spread, it is unclean. You must burn it with fire. It is a fungus, whether it is on the inside or outside.

56 But if, after it is washed, the priest sees that the infection has faded, he will tear the infected part out of the cloth, the weaving, or the skin.
