Joshua 24:25–27
On that day Joshua made a covenant for the people, and there at Shechem he established for them a statute and ordinance. / 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 that was near the sanctuary of the LORD. / And Joshua said to all the people, “You see this stone. It will be a witness against us, for it has heard all the words the LORD has spoken to us, and it will be a witness against you if you ever deny your God.”
Judges 9:6
Then all the leaders of Shechem and Beth-millo gathered beside the oak at the pillar in Shechem and proceeded to make Abimelech their king.
