Joshua 24:20-24

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. And the people said unto Joshua, Nay; but we will serve Jehovah. And Joshua said unto the people, Ye are witnesses against yourselves that ye have chosen you Jehovah, to serve him. And they said, We are witnesses. Now therefore put away, said he, the foreign gods which are among you, and incline your heart unto Jehovah, the God of Israel. And the people said unto Joshua, Jehovah our God will we serve, and unto his voice will we hearken.
