Leviticus 13:54 Meaning and Commentary

Leviticus 13:54

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:

56 And if the priest sees that the mark is less bright after the washing, then let him have it cut out of the clothing or the leather or from the threads of the material:
