'Separated' in the Bible

“Thus you shall keep the sons of Israel separated from their uncleanness, so that they will not die in their uncleanness by their defiling My tabernacle that is among them.”

Hence I have said to you, “You are to possess their land, and I Myself will give it to you to possess it, a land flowing with milk and honey.” I am the Lord your God, who has separated you from the peoples.

You are therefore to make a distinction between the clean animal and the unclean, and between the unclean bird and the clean; and you shall not make yourselves detestable by animal or by bird or by anything that creeps on the ground, which I have separated for you as unclean.
