Joshua 9:19-23

But all the princes said unto all the congregation, We have sworn unto them by the LORD God of Israel: now therefore we may not touch them.

This we will do to them; we will even let them live, lest wrath be upon us, because of the oath which we sware unto them.

And the princes said unto them, Let them live; but let them be hewers of wood and drawers of water unto all the congregation; as the princes had promised them.

And Joshua called for them, and he spake unto them, saying, Wherefore have ye beguiled us, saying, We are very far from you; when ye dwell among us?

Now therefore ye are cursed, and there shall none of you be freed from being bondmen, and hewers of wood and drawers of water for the house of my God.
