14 When thou comest unto the land which Jehovah thy God giveth thee, and shalt possess it, and shalt dwell therein, and shalt say, I will set a king over me, like all the nations that are about me; 15 thou shalt only set him king over thee whom Jehovah thy God will choose: from among thy brethren shalt thou set a king over thee; thou mayest not set a foreigner over thee, who is not thy brother. 16 Only he shall not multiply horses to himself, nor lead back the people to Egypt, to multiply horses; for Jehovah hath said unto you, Ye shall not return again any more that way. 17 Neither shall he multiply wives to himself, that his heart turn not away; neither shall he greatly multiply to himself silver and gold. 18 And it shall be, when he sitteth upon the throne of his kingdom, that he shall write for himself a copy of this law in a book out of that which is before the priests, the Levites; 19 and it shall be with him, and he shall read therein all the days of his life; that he may learn to fear Jehovah his God, to keep all the words of this law and these statutes, to do them; 20 that his heart be not lifted up above his brethren, and that he turn not aside from the commandment, to the right hand, or to the left; that he may prolong his days in his kingdom, he, and his sons, in the midst of 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.
