Joshua 9:24-27

They replied, “We did it because we—your servants—were clearly told that the LORD your God commanded his servant Moses to give you this entire land and to destroy all the people living in it. So we feared greatly for our lives because of you. That is why we have done this. Now we are at your mercy—do to us whatever you think is right.” So Joshua did not allow the people of Israel to kill them. But that day he made the Gibeonites the woodcutters and water carriers for the community of Israel and for the altar of the LORD—wherever the LORD would choose to build it. And that is what they do to this day.
