Joshua 24:21

17 For the LORD our God brought us and our fathers out of the land of Egypt, out of the house of slavery, and performed these great signs before our eyes. He also protected us throughout our journey and among all the nations through which we traveled.

18 And the LORD drove out before us all the nations, including the Amorites who lived in the land. We too will serve the LORD, because He is our God!”

19 But Joshua said to the people, “You are not able to serve the LORD, for He is a holy God; He is a jealous God; He will not forgive your rebellion or your sins.

20 If you forsake the LORD and serve foreign gods, He will turn and bring disaster on you and consume you, even after He has been good to you.”

21 “No!” replied the people. “We will serve the LORD!”

22 Then Joshua told them, “You are witnesses against yourselves that you have chosen to serve the LORD.” “We are witnesses!” they said.

23 “Now, therefore,” he said, “get rid of the foreign gods among you and incline your hearts to the LORD, the God of Israel.”

24 So the people said to Joshua, “We will serve the LORD our God and obey His voice.”

25 On that day Joshua made a covenant for the people, and there at Shechem he established for them a statute and ordinance.
