Joshua 9:17-21

¹⁷And the children of Israel departed and came to their cities; and their cities were Gabaon, and Kephira, and Berot, and the cities of Jarin.

¹⁸And the children of Israel fought not with them, because all the princes sware to them by the Lord God of Israel; and all the congregation murmured at the princes.

¹⁹And the princes said to all the congregation: We have sworn to them by the Lord God of Israel, and now we shall not be able to touch them.

²⁰This we will do; take them alive, and we will preserve them: so there shall not be wrath against us by reason of the oath which we swore to them.

²¹They shall live, and shall be hewers of wood and drawers of water to all the congregation, as the princes said to them.
