Joshua 24:24-27

And the people said to Joshua, “We will serve the LORD our God and obey him.” On that day Joshua made a covenant for the people, and there at Shechem he reaffirmed for them decrees and laws. And Joshua recorded these things in the Book of the Law of God. Then he took a large stone and set it up there under the oak near the holy place of the LORD. “See!” he said to all the people. “This stone will be a witness against us. It has heard all the words the LORD has said to us. It will be a witness against you if you are untrue to your God.”
