Deuteronomy 20:13

Holy Bible: Easy-to-Read Version

And when the Lord your God lets you take the city, you must kill all the men in it.

See the chapter Copy

Now where are my enemies? Where are the people who did not want me to be king? Bring my enemies here and kill them. I will watch them die.’”

The Lord said to my lord, “Sit at my right side, while I put your enemies under your control.”

But if the city refuses to make peace with you and fights against you, you should surround the city.
