Joshua 24:25

23“Now therefore put away the foreign gods which are among you, and incline your heart to the LORD, the God of Israel.”

24The people said to Joshua, “We will serve the LORD our God, and we will listen to his voice.”

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

26Joshua wrote these words in the book of the law of God; and he took a great stone, and set it up there under the oak that was by the sanctuary of the LORD.

27Joshua said to all the people, “Behold, this stone shall be a witness against us, for it has heard all the LORD’s words which he spoke to us. It shall be therefore a witness against you, lest you deny your God.”
