1 Samuel 8:7-9

7And the LORD said to Samuel, “Listen to the voice of the people in all that they say to you. For it is not you they have rejected, but they have rejected Me as their king. 8Just as they have done from the day I brought them up out of Egypt until this day, forsaking Me and serving other gods, so they are doing to you. 9Now listen to their voice; but you must solemnly warn them and show them the manner of the king who will reign over them.”
