Deuteronomy 17:17-19 Living Bible (TLB)
17 He must not have too many wives, lest his heart be turned away from the Lord, neither shall he be excessively rich.
18 “And when he has been crowned and sits upon his throne as king, then he must copy these laws from the book kept by the Levite-priests. 19 That copy of the laws shall be his constant companion. He must read from it every day of his life so that he will learn to respect the Lord his God by obeying all of his commands.
