Albert Barnes Commentary Leviticus 20:22-26

"Ye shall therefore keep all my statutes, and all mine ordinances, and do them; that the land, whither I bring you to dwell therein, vomit you not out. And ye shall not walk in the customs of the nation, which I cast out before you: for they did all these things, and therefore I abhorred them. But I have said unto you, Ye shall inherit their land, and I will give it unto you to possess it, a land flowing with milk and honey: I am Jehovah your God, who hath separated you from the peoples. Ye shall therefore make a distinction between the clean beast and the unclean, and between the unclean fowl and the clean: and ye shall not make your souls abominable by beast, or by bird, or by anything wherewith the ground teemeth, which I have separated from you as unclean. And ye shall be holy unto me: for I, Jehovah, am holy, and have set you apart from the peoples, that ye should be mine." — Leviticus 20:22-26 (ASV)

The ground is here again stated on which all these laws of holiness should be obeyed. See the note on Leviticus 18:24-30.

Leviticus 20:24: Compare the margin reference.

Leviticus 20:25 and 20:26: The distinction between clean and unclean for the whole people, and not for any mere section of it, was one great typical mark of “the kingdom of priests, the holy nation.” See the note on Leviticus 11:42.

Leviticus 20:25: Any manner of living thing that creepeth - Rather, any creeping thing; that is, any vermin. See Leviticus 11:20-23. The reference in this verse is to dead animals, not to the creatures when alive.
