Deuteronomy 20:17-19

Amplified Bible, Classic Edition

¹⁷ But you shall utterly exterminate them, the Hittites, the Amorites, the Canaanites, the Perizzites, the Hivites, and the Jebusites, as the Lord your God has commanded you,

¹⁸ So that they may not teach you all the abominable practices they have carried on for their gods, and so cause you to sin against the Lord your God.

¹⁹ When you besiege a city for a long time, making war against it to take it, you shall not destroy its trees by using an ax on them, for you can eat their fruit; you must not cut them down, for is the tree of the field a man, that it should be besieged by you?
