Deuteronomy 17:13

according to the tenor of the law which they shall teach you, and according to the judgment which they shall tell you, you shall do; you shall not turn aside from the sentence which they shall show you, to the right hand, nor to the left.

The man who does presumptuously, in not listening to the priest who stands to minister there before Yahweh your God, or to the judge, even that man shall die: and you shall put away the evil from Israel.

When you are come to the land which Yahweh your God gives you, and shall possess it, and shall dwell therein, and shall say, "I will set a king over me, like all the nations that are around me;

you shall surely set him king over yourselves, whom Yahweh your God shall choose: one from among your brothers you shall set king over you; you may not put a foreigner over you, who is not your brother.
