10 and thou hast done according to the tenor of the word which they declare to thee ('they' of that place which Jehovah doth choose; and thou hast observed to do according to all that they direct thee. 11 'According to the tenor of the law which they direct thee, and according to the judgment which they say to thee thou dost do; thou dost not turn aside from the word which they declare to thee, right or left. 12 And the man who acteth with presumption, so as not to hearken unto the priest (who is standing to serve there Jehovah thy God), or unto the judge, even that man hath died, and thou hast put away the evil thing from Israel, 13 and all the people do hear and fear, and do not presume any more.
14 'When thou comest in unto the land which Jehovah thy God is giving to thee, and hast possessed it, and dwelt in it, and thou hast said, Let me set over me a king like all the nations which 'are' round about me,— 15 thou dost certainly set over thee a king on whom Jehovah doth fix; from the midst of thy brethren thou dost set over thee a king; thou art not able to set over thee a stranger, who is not thy brother. 16 'Only, he doth not multiply to himself horses, nor cause the people to turn back to Egypt, so as to multiply horses, seeing Jehovah hath said to you, Ye do not add to turn back in this way any more. 17 And he doth not multiply to himself wives, and his heart doth not turn aside, and silver and gold he doth not multiply to himself—exceedingly. 18 'And it hath been, when he sitteth on the throne of his kingdom, that he hath written for himself the copy of this law, on a book, from 'that' before the priests the Levites, 19 and it hath been with him, and he hath read in it all days of his life, so that he doth learn to fear Jehovah his God, to keep all the words of this law, and these statutes, to do them; 20 so that his heart is not high above his brethren, and so as not to turn aside from the command, right or left, so that he prolongeth days over his kingdom, he and his sons, in the midst of Israel.

Commentary on Deuteronomy 17:8-13
(Read Deuteronomy 17:8-13)
Courts of judgment were to be set up in every city. Though their judgment had not the Divine authority of an oracle, it was the judgment of wise, prudent, experienced men, and had the advantage of a Divine promise.
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.
