Joshua 24:25-27

25So Joshua made a covenant with the people that day, and made for them a statute and an ordinance in Shechem.

26Then Joshua wrote these words in the Book of the Law of God. And he took a large stone, and set it up there under the oak that was by the sanctuary of the Lord.

27And Joshua said to all the people, “Behold, this stone shall be a witness to us, for it has heard all the words of the Lord which He spoke to us. It shall therefore be a witness to you, lest you deny your God.”
