Deuteronomy 20:10-12

Common English Bible

¹⁰ When you approach a city to fight against it, you should first extend peaceful terms to it. ¹¹ If the city responds with peaceful terms and surrenders to you, then all the people in the city will serve you as forced laborers. ¹² However, if the city does not negotiate peacefully with you but makes war against you, you may attack it.
