Deuteronomy 17:16-18

The Voice

¹⁶ Although an Israelite, he must not try to build a strong army by collecting large herds of horses for his cavalry troops and a chariot corps. The king must certainly not send people back to Egypt to get large herds of horses, because the Lord has commanded you, “Don’t ever go back that way again!” ¹⁷ This king must not have many wives. If he takes foreign wives in marriage alliances, they could turn his heart away from the Lord and lead him to worship foreign gods. And the king must not accumulate great quantities of silver and gold for himself.

¹⁸ As soon as this king takes the royal throne, he must write out a copy of this law for himself on a scroll with the Levitical priests looking on.
