Joshua 24:21-25

And the people said to Joshua, “No, but we will serve the Lord.”

So Joshua said to the people, “You are witnesses against yourselves that you have chosen for yourselves the Lord, to serve Him.” And they said, “We are witnesses.”

“Now then, do away with the foreign gods which are in your midst, and incline your hearts to the Lord, the God of Israel.”

And the people said to Joshua, “We will serve the Lord our God and obey His voice.”

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