'Defile' in the Bible

You must expel both men and women; you must put them outside the camp, so that they will not defile their camps, among which I live."

He must not defile himself even for his father or his mother or his brother or his sister if they die, because the separation for his God is on his head.

Therefore do not defile the land that you will inhabit, in which I live, for I the Lord live among the Israelites."
