Joshua 24:25-28

So Joshua made a covenant with the people that day, and set them a statute and an ordinance in Shechem. And Joshua 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 Jehovah. And Joshua said unto all the people, Behold, this stone shall be a witness against us; for it hath heard all the words of Jehovah which he spake unto us: it shall be therefore a witness against you, lest ye deny your God. So Joshua sent the people away, every man unto his inheritance.
