“When a leprous disease appears in the clothing, in woolen or linen cloth, in a warp or woof of linen or wool, or in a skin or in anything made of skin, if the disease shows greenish or reddish in the garment, whether in a warp or woof or in skin or in anything made of skin, it is a leprous disease and shall be shown to the priest. The priest shall examine the disease. He shall put the diseased article aside for seven days. He shall examine the disease on the seventh day. If the disease has spread in the cloth, in the warp or woof, or in the skin, whatever is the use of the skin, this is a spreading leprous disease. It is unclean. He shall burn the clothing, whether diseased in warp or woof, woolen or linen, or anything of skin, for it is a malignant spreading leprous disease. It shall be burned in fire.”
The lepers could wear woolen, linen, or skin clothing. If the disease showed greenish or reddish in the garment, it had to be shown to the priest. This warp and wool refers to the threads in a fabric. The priest was to wait 7 days to see if this mold, mildew, or stain had spread on the cloth. If it had, he burnt the clothing. The clothing was unclean because of the leprosy.
“If the priest makes an examination, and the disease has not spread in the clothing, in the warp or woof, or in anything of skin, then the priest shall command them to wash the article in which the disease appeared. He shall put it aside seven days more. The priest shall examine the diseased article after it has been washed. If the diseased spot has not changed color, though the disease has not spread, it is unclean. You shall burn it in fire, whether the leprous spot is on the inside or the outside.”
If the disease had not spread, you were to wash the article and put it aside 7 days more. If there is no change after the washing, then burn it. Even after this, it is still unclean.
“If the priest makes an examination, and the disease has abated after it is washed, he shall tear the spot out of the cloth, in the warp or woof, or out of the skin. If it appears again in the garment, in the warp or woof, or in anything of skin, it is spreading. You shall burn with fire that in which the disease appears. But the cloth, warp or woof, or anything of skin from which the disease disappears when you have washed it, shall then be washed a second time. Then it shall be clean. This is the ritual law for a leprous disease in a cloth of wool or linen, either in warp or woof, or in anything of skin, to decide whether it is clean or unclean.”
If there is nothing after it has been washed, the priest shall tear the spot out of the cloth. If it still appears, that you burn it. However, if everything is okay, then it should be washed a second time. Then it shall be clean. There were very specific rules about what made a garment clean or unclean.
