Joshua 24:18-20

American Standard Version

¹⁸ and Jehovah drove out from before us all the peoples, even the Amorites that dwelt in the land: therefore we also will serve Jehovah; for he is our God.

¹⁹ And Joshua said unto the people, Ye cannot serve Jehovah; for he is a holy God; he is a jealous God; he will not forgive your transgression nor your sins. ²⁰ If ye forsake Jehovah, and serve foreign gods, then he will turn and do you evil, and consume you, after that he hath done you good.
