Joshua 24:25-27

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

26Then Joshua wrote these words in the scroll of the Torah of God. Also he took a great stone and set it up there under the oak that was by the Sanctuary of Adonai.

27Joshua said to all the people, “Behold, this stone will be a witness to us. For it has heard all the words of Adonai which He has spoken to us. So it will be a witness to you, lest you deny your God.”
