47 And, when, in a garment, there is a plague-spot of leprosy, - whether in a garment of wool, or a garment of flax; 48 either in warp or in weft, made with flax, or with wool, - or in a skin, or in anything wrought of skin; 49 and the spot cometh to be of a greenish yellow or reddish, in the garment or in the skin, whether in warp or in weft, or in any utensil of skin, the plague-spot of leprosy, it is, - and shall be shown unto the priest; 50 and the priest shall view the spot, - and shall shut up him that is plagued seven days; 51 then shall he view the spot, on the seventh day if the spot hath spread in the garment whether in warp or in weft, or in the skin, or anything which may be made of skin for service, the spot is a fretting leprosy, unclean, it is. 52 Then shall he burn up the garment whether it be m the warp or the weft in wool or in flax, or any utensil of skin, wherein shall be the plague-spot, - for, a fretting leprosy, it is, in fire, shall it be burnt up.
53 But if the priest shall take a view, and lo! the spot has not spread, in the garment, either in warp or in weft, - or in any utensil of skin, 54 then shall the priest give command, and they shall wash that wherein is the spot, - and he shall shut it up seven days more; 55 then shall the priest take a view after the plagued garment hath been washed and lo! if the spot hath not changed its look, then though the spot hath not spread, yet unclean, it is, in the fire, shalt thou burn it up, - a sunken spot, it is, in the back thereof, or in the front thereof.
56 And, if the priest hath taken a view, and lo! the spot is, faint, since it hath been washed, then shall he rend it out of the garment, or out of the skin, whether out of the warp or out of the weft; 57 and, if it appear still in the garment - either in the warp or in the weft, or in any utensil of skin, a breaking out, it is, - in the fire, shalt thou burn up that wherein is the plague. 58 But, as for the garment - whether the warp or the weft or any utensil of skin which thou shalt wash, and the plague shall depart therefrom, then shall it be washed a second time, and shall be clean.
59 This, is the law as to the plague-spot of leprosy, in a garment of wool or of flax, whether in the warp or the weft, or in any utensil of skin, - To pronounce it clean, or to pronounce it unclean.
