De 17:14-20. THE ELECTION AND DUTY OF A KING.

      14. When thou . . . shalt say, I will set a king over me--In the following passage Moses prophetically announces a revolution which should occur at a later period in the national history of Israel. No sanction or recommendation was indicated; on the contrary, when the popular clamor had effected that constitutional change on the theocracy by the appointment of a king, the divine disapproval was expressed in the most unequivocal terms (1Sa 8:7). Permission at length was granted, God reserving to Himself the nomination of the family and the person who should be elevated to the regal dignity (1Sa 9:15; 10:24; 16:12; 1Ch 28:4). In short, Moses foreseeing that his ignorant and fickle countrymen, insensible to their advantages as a peculiar people, would soon wish to change their constitution and be like other nations, provides to a certain extent for such an emergency and lays down the principles on which a king in Israel must act. He was to possess certain indispensable requisites. He was to be an Israelite, of the same race and religion, to preserve the purity of the established worship, as well as be a type of Christ, a spiritual king, one of their brethren.
