Deuteronomy 17:13

10 And thou shalt do according to the sentence, which they of that place which the LORD shall choose shall show thee; and thou shalt observe to do according to all that they inform thee:

11 According to the sentence of the law which they shall teach thee, and according to the judgment which they shall tell thee, thou shalt do: thou shalt not decline from the sentence which they shall show thee, [to] the right hand, nor [to] the left.

12 And the man that will do presumptuously, and will not hearken to the priest that standeth to minister there before the LORD thy God, or to the judge, even that man shall die: and thou shalt remove the evil from Israel.

13 And all the people shall hear, and fear, and do no more presumptuously.

14 When thou art come into the land which the LORD thy God giveth thee, and shalt possess it, and shalt dwell in it, and shalt say, I will set a king over me, like as all the nations that [are] about me;

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 stranger over thee, who [is] not thy brother.

16 But 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 to you, ye shall henceforth return no more that way.
