Leviticus 20:23-25

Revised Standard Version Catholic Edition

²³ And you shall not walk in the customs of the nation which I am casting out before you; for they did all these things, and therefore I abhorred them. ²⁴ But I have said to you, ‘You shall inherit their land, and I will give it to you to possess, a land flowing with milk and honey.’ I am the Lord your God, who have separated you from the peoples. ²⁵ You shall therefore make a distinction between the clean beast and the unclean, and between the unclean bird and the clean; you shall not make yourselves abominable by beast or by bird or by anything with which the ground teems, which I have set apart for you to hold unclean.
