Joshua 9:19-23

But 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.

This 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.”

So the leaders said to them, “Let them live.” And they became gatherers of firewood and labor to draw water for the whole congregation, just as the leaders had spoken to them.

Then Joshua called for them and spoke to them, saying, “Why have you deceived us, saying, ‘We are very far from you,’ when you are living within our land?

Now therefore, you are cursed, and you will never cease to be slaves, both gatherers of firewood and labor to draw water for the house of my God.”
