Leviticus 13:51-52

13:51 He must then examine the infection on the seventh day. If the infection has spread in the garment, or in the warp, or in the woof, or in the leather – whatever the article into which the leather was made ¹  – the infection is a malignant disease. It is unclean. 13:52 He must burn the garment or the warp or the woof, whether wool or linen, or any article of leather which has the infection in it. Because it is a malignant disease it must be burned up in the fire.

¹ tn Heb “to all which the leather was made into a handiwork.”
