Deuteronomy 17:16-17

JPS_ASV_Byz(i) 16 Only he shall not multiply horses to himself, nor cause the people to return to Egypt, to the end that he should multiply horses; forasmuch as the LORD hath said unto you: 'Ye shall henceforth return no more that way.' 17 Neither shall he multiply wives to himself, that his heart turn not away; neither shall he greatly multiply to himself silver and gold.
