| Geneva Study Bible And it shall be, when he sitteth upon the throne of his kingdom, that he shall write him a copy of this {m} law in a book out of that which is before the {n} priests the Levites: (m) Meaning, Deuteronomy. (n) He shall cause it to be written by them, or he shall write it by their example. Wesley's Notes 17:18 He shall write - With his own hand, as the Jews say. Out of that - Out of the original, which was carefully kept by the priests in the sanctuary, that it might be a perfect copy, and that it might have the greater influence upon him, coming to him as from the hand and presence of God. Jamieson-Fausset-Brown Bible Commentary 18-20. he shall write him a copy of this law in a book-The original scroll of the ancient Scriptures was deposited in the sanctuary under the strict custody of the priests (see on [150]De 31:26; [151]2Ki 22:8). Each monarch, on his accession, was to be furnished with a true and faithful copy, which he was to keep constantly beside him, and daily peruse it, that his character and sentiments being cast into its sanctifying mould, he might discharge his royal functions in the spirit of faith and piety, of humility and a love or righteousness. Matthew Henry's Concise Commentary 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. |
