Deuteronomy 20:11

And it shall be, if it make thee answer of peace, and open unto thee, then it shall be, that all the people that is found therein shall be tributaries unto thee, and they shall serve thee.

It shall be, if it make you answer of peace, and open to you, then it shall be, that all the people who are found therein shall become tributary to you, and shall serve you.

And it shall be, if it make thee answer of peace, and open unto thee, then it shall be, that all the people that are found therein shall become tributary unto thee, and shall serve thee.

and it hath been, if Peace it answer thee, and hath opened to thee, then it hath come to pass -- all the people who are found in it are to thee for tributaries, and have served thee.

If they accept your offer of peace and open their gates, all the people there will become forced laborers to serve you.
