Joshua 9:19-21

19But all the leaders said to the whole congregation, “We have sworn to them by the Lord, the God of Israel, and now we cannot touch them. 20This we will do to them, even let them live, so that wrath will not be on us because of the oath which we swore to them.” 21So the leaders said to them, “Let them live.” And they became 1gatherers of firewood and 2labor to draw water for the whole congregation, just as the leaders had spoken to them.
