'Defile' in the Bible

both male and female shall ye put out, without the camp shall ye put them; that they defile not their camp, in the midst whereof I dwell.

And if any man die very suddenly beside him, and he defile the head of his separation; then he shall shave his head in the day of his cleansing, on the seventh day shall he shave it.

And thou shalt not defile the land which ye inhabit, in the midst of which I dwell: for I, Jehovah, dwell in the midst of the children of Israel.
