Joshua 24:14-16, 24-27

“Now, therefore, fear the LORD and serve Him in sincerity and in truth; remove the gods which your fathers served on the other side of the [Euphrates] River and in Egypt, and serve the LORD. If it is unacceptable in your sight to serve the LORD, choose for yourselves this day whom you will serve: whether the gods which your fathers served that were on the other side of the River, or the gods of the Amorites in whose land you live; but as for me and my house, we will serve the LORD.” The people answered, “Far be it from us to abandon (reject) the LORD to serve other gods

The people said to Joshua, “We will serve the LORD our God and we will listen to and obey His voice.” So Joshua made a covenant with the people that day, and made for them a statute and an ordinance at Shechem. And Joshua wrote these words in the Book of the Law of God. Then he took a large stone and set it up there under the oak that was in [the courtyard of] the sanctuary of the LORD. Joshua then said to all the people, “Look, this stone shall serve as a witness against us, for it has heard all the words of the LORD which He spoke to us; so it shall be a witness against you, so that [afterward] you do not deny your God.”
