Deuteronomy 17:14-16

Young's Literal Translation

¹⁴ `When thou comest in unto the land which Jehovah thy God is giving to thee, and hast possessed it, and dwelt in it, and thou hast said, Let me set over me a king like all the nations which [are] round about me, --

¹⁵ thou dost certainly set over thee a king on whom Jehovah doth fix; from the midst of thy brethren thou dost set over thee a king; thou art not able to set over thee a stranger, who is not thy brother.

¹⁶ `Only, he doth not multiply to himself horses, nor cause the people to turn back to Egypt, so as to multiply horses, seeing Jehovah hath said to you, Ye do not add to turn back in this way any more.
