'Contaminated' in the Bible
Do not become contaminated by any creature that swarms; do not become unclean or defiled by them.
“If a fabric is contaminated with mildew—in wool or linen fabric,
The priest is to examine the contamination and quarantine the contaminated fabric for seven days.
He is to burn the fabric, the warp or woof in wool or linen, or any leather article, which is contaminated. Since it is harmful mildew it must be burned up.
the priest is to order whatever is contaminated to be washed and quarantined for another seven days.
After it has been washed, the priest is to reexamine the contamination. If the appearance of the contaminated article has not changed, it is unclean. Even though the contamination has not spread, you must burn up the fabric. It is a fungus on the front or back of the fabric.
“If the priest examines it, and the contamination has faded after it has been washed, he must cut the contaminated section out of the fabric, the leather, or the warp or woof.
But if it reappears in the fabric, the warp or woof, or any leather article, it has broken out again. You must burn up whatever is contaminated.
