Deuteronomy 17:15

Thou shalt in any wise set [him] king over thee, whom the LORD thy God shall choose: [one] from among thy brethren shalt thou set king over thee: thou mayest not set a {i} stranger over thee, which [is] not thy brother.

(i) Who is not from your nation, lest he change true religion into idolatry, and bring you to slavery.
