Neither shall he multiply wives to himself, that his heart {l} turn not away: neither shall he greatly multiply to himself silver and gold.

(l) From the Law of God.

Wesley's Notes

17:17 Turn away - From God and his law.

Jamieson-Fausset-Brown Bible Commentary

17. Neither shall he multiply wives to himself, that his heart turn not away-There were the strongest reasons for recording an express prohibition on this point, founded on the practice of neighboring countries in which polygamy prevailed, and whose kings had numerous harems; besides, the monarch of Israel was to be absolutely independent of the people and had nothing but the divine law to restrain his passions. The mischievous effects resulting from the breach of this condition were exemplified in the history of Solomon and other princes, who, by trampling on the restrictive law, corrupted themselves as well as the nation.

neither shall he greatly multiply . silver and gold-that is, the kings were forbidden to accumulate money for private purposes.

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.
