'Defiling' in the Bible

“Thus you shall separate the Israelites from their uncleanness, so that they do not die in their uncleanness by their defiling My tabernacle that is among them.”

I will also set My face against that man [opposing him, withdrawing My protection from him] and will cut him off from his people [excluding him from the atonement made for them], because he has given some of his children to Molech, so as to defile My sanctuary and profane My holy name.

He shall not eat that which dies [of natural causes] or is torn by a predator, becoming unclean by it; I am the Lord.
