Instructions concerning a King

14 "You are about to enter the land the Lord your God is giving you. When you take it over and settle there, you may think, 'We should select a king to rule over us like the other nations around us.' 15 If this happens, be sure to select as king the man the Lord your God chooses. You must appoint a fellow Israelite; he may not be a foreigner. 16 "The king must not build up a large stable of horses for himself or send his people to Egypt to buy horses, for the Lord has told you, 'You must never return to Egypt.' 17 The king must not take many wives for himself, because they will turn his heart away from the Lord . And he must not accumulate large amounts of wealth in silver and gold for himself. 18 "When he sits on the throne as king, he must copy for himself this body of instruction on a scroll in the presence of the Levitical priests. 19 He must always keep that copy with him and read it daily as long as he lives. That way he will learn to fear the Lord his God by obeying all the terms of these instructions and decrees. 20 This regular reading will prevent him from becoming proud and acting as if he is above his fellow citizens. It will also prevent him from turning away from these commands in the smallest way. And it will ensure that he and his descendants will reign for many generations in Israel.

Commentary on Deuteronomy 17:14-20

(Read Deuteronomy 17:14-20)

God himself was in a particular manner Israel's King; and if they set another over them, it was necessary that he should choose the person. Accordingly, when the people desired a king, they applied to Samuel, a prophet of the Lord. In all cases, God's choice, if we can but know it, should direct, determine, and overrule ours. Laws are given for the prince that should be elected. He must carefully avoid every thing that would turn him from God and religion. Riches, honours, and pleasures, are three great hinderances of godliness, (the lusts of the flesh, the lusts of the eye, and the pride of life,) especially to those in high stations; against these the king is here warned. The king must carefully study the law of God, and make that his rule; and having a copy of the Scriptures of his own writing, must read therein all the days of his life. It is not enough to have Bibles, but we must use them, use them daily, as long as we live. Christ's scholars never learn above their Bibles, but will have constant occasion for them, till they come to that world where knowledge and love will be made perfect. The king's writing and reading were as nothing, if he did not practise what he wrote and read. And those who fear God and keep his commandments, will fare the better for it even in this world.
