When you enter the land the LORD your God is giving you and have taken possession of it and settled in it, and you say, “Let us set a king over us like all the nations around us,”
be sure to appoint over you a king the LORD your God chooses. He must be from among your fellow Israelites. Do not place a foreigner over you, one who is not an Israelite.
The king, moreover, must not acquire great numbers of horses for himself or make the people return to Egypt to get more of them, for the LORD has told you, “You are not to go back that way again.”
He must not take many wives, or his heart will be led astray. He must not accumulate large amounts of silver and gold.
