Devarim 20:9-11

Orthodox Jewish Bible

⁹ And it shall be, when the shoterim have made an end of speaking unto the people that they shall appoint sarei tzvaos to lead the people.

¹⁰ When thou comest nigh unto a town to fight against it, then proclaim an offer of shalom unto it.

¹¹ And it shall be, if it make thee answer of shalom, and open unto thee, then it shall be, that kol haAm that is found therein shall be servants, placed under tribute unto thee, and they shall serve thee.
