Deuteronomy 17:14-16

Amplified Bible

¹⁴ “When you enter the land which the Lord your God is giving you, and you take possession of it and live there, and you say, ‘I will set a king over me like all the nations who are around me,’ ¹⁵ you shall most certainly set a king over you whom the Lord your God chooses. You shall set a king over you from among your countrymen (brothers); you may not choose a foreigner [to rule] over you who is not your countryman. ¹⁶ Further, he shall not ^[a]acquire many [war] horses for himself, nor make the people return to Egypt in order to acquire horses [to expand his military power], since the Lord said to you, ‘You shall never return that way again.’
