Joshua 9:22-23, 27

Joshua summoned the Gibeonites and asked them, “Why did you deceive us? You told us that you lived very far from us, but we now know for a fact that you live right here near us. Therefore, we will spare your lives, but you will live under a curse, and you will be condemned to perpetual servitude. You will serve the house of my God by cutting wood and carrying water for us.”

That day, he made them woodcutters and water carriers to serve the community of Israel for the altar of YAHWEH at his divinely chosen place. And that is what they do to this day.
