Joshua 24:24-27

²⁴And the people said unto Joshua, Jehovah our God will we serve, and unto his voice will we hearken.

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

²⁶And 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.

²⁷And 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.
