Joshua 24:25-27 The Message (MSG)
25-26 Joshua completed a Covenant for the people that day there at Shechem. He made it official, spelling it out in detail. Joshua wrote out all the directions and regulations into the Book of The Revelation of God. Then he took a large stone and set it up under the oak that was in the holy place of God.
27 Joshua spoke to all the people: “This stone is a witness against us. It has heard every word that God has said to us. It is a standing witness against you lest you cheat on your God.”
