Deuteronomy 20:11-13

New Revised Standard Version Updated Edition

¹¹ If it accepts your terms of peace and surrenders to you, then all the people in it shall serve you at forced labor. ¹² But if it does not accept your terms of peace and makes war against you, then you shall besiege it, ¹³ and when the Lord your God gives it into your hand, you shall put all its males to the sword.
