Deuteronomy 17:16-17
Deuteronomy 17:16-17 NASB1995
Moreover, he shall not multiply horses for himself, nor shall he cause the people to return to Egypt to multiply horses, since the LORD has said to you, ‘You shall never again return that way.’ He shall not multiply wives for himself, or else his heart will turn away; nor shall he greatly increase silver and gold for himself.
