Deuteronomy 14:21

14:21 You may not eat any corpse, though you may give it to the resident foreigner who is living in your villages and he may eat it, or you may sell it to a foreigner. You are a people holy to the Lord your God. Do not boil a young goat in its mother’s milk.

Deuteronomy 20:19

20:19 If you besiege a city for a long time while attempting to capture it, you must not chop down its trees, for you may eat fruit from them and should not cut them down. A tree in the field is not human that you should besiege it!
