50 And the priest shall look upon the plague, and shut up [that which hath] the plague seven days:

52 And he shall burn the garment, whether the warp or the woof, in woollen or in linen, or anything of skin, wherein the plague is: for it is a fretting leprosy; it shall be burnt in the fire.

53 And if the priest shall look, and, behold, the plague be not spread in the garment, either in the warp, or in the woof, or in anything of skin;
