Deuteronomy 20:11-13

New Catholic Bible

¹¹ If they accept your terms of peace and open their gates to you, then all the people who live there shall be subject to forced labor done on your behalf. ¹² If they refuse your terms of peace, then you will do battle with them, besieging that city. ¹³ When the Lord, your God, delivers it into your hands, you shall put every man in it to death.
