Joshua 24:14-24 (NKJV)
14“Now therefore, fear the Lord, serve Him in sincerity and in truth, and put away the gods which your fathers served on the other side of the River and in Egypt. Serve the Lord! 15And if it seems evil to you 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 dwell. But as for me and my house, we will serve the Lord.”
16So the people answered and said: “Far be it from us that we should forsake the Lord to serve other gods; 17for the Lord our God is He who brought us and our fathers up out of the land of Egypt, from the house of bondage, who did those great signs in our sight, and preserved us in all the way that we went and among all the people through whom we passed. 18And the Lord drove out from before us all the people, including the Amorites who dwelt in the land. We also will serve the Lord, for He is our God.”
19But Joshua said to the people, “You cannot serve the Lord, for He is a holy God. He is a jealous God; He will not forgive your transgressions nor your sins. 20If you forsake the Lord and serve foreign gods, then He will turn and do you harm and consume you, after He has done you good.”
21And the people said to Joshua, “No, but we will serve the Lord!”
22So Joshua said to the people, “You are witnesses against yourselves that you have chosen the Lord for yourselves, to serve Him.”
And they said, “We are witnesses!”
23“Now therefore,” he said, “put away the foreign gods which are among you, and incline your heart to the Lord God of Israel.”
24And the people said to Joshua, “The Lord our God we will serve, and His voice we will obey!”
