Deuteronomy 20:18-20

Names of God Bible

¹⁸ Otherwise, they will teach you to do all the disgusting things they do for their gods, and you will sin against Yahweh your Elohim.

¹⁹ This is what you must do whenever you blockade a city for a long time in order to capture it in war. Don’t harm any of its fruit trees with an ax. You can eat the fruit. Never cut those trees down, because the trees of the field are not people you have come to blockade. ²⁰ You may destroy trees that you know are not fruit trees. You may cut them down and use them in your blockade until you capture the city.
