Deu 17:14-17
Choice and Right of the King. - Deu 17:14, Deu 17:15. If Israel, when dwelling in the land which was given it by the Lord for a possession, should wish to appoint a king, like all the nations round about, it was to appoint the man whom Jehovah its God should choose, and that from among its brethren, i.e., from its own people, not a foreigner or non-Israelite. The earthly kingdom in Israel was not opposed to the theocracy, i.e., to the rule of Jehovah as king over the people of His possession, provided no one was made king but the person whom Jehovah should choose. The appointment of a king is not commanded, like the institution of judges (Deu 16:18), because Israel could exist under the government of Jehovah, even without an earthly king; it is simply permitted, in case the need should arise for a regal government. There was no necessity to describe more minutely the course to be adopted, as the people possessed the natural provision for the administration of their national affairs in their well-organized tribes, by whom this point could be decided. Moses also omits to state more particularly in what way Jehovah would make known the choice of the king to be appointed. The congregation, no doubt, possessed one means of asking the will of the Lord in the Urim and Thummim of the high priest, provided the Lord did not reveal His will in a different manner, namely through a prophet, as He did in the election of Saul and David (1 Sam 8-9, and 16). The commandment not to choose a foreigner, acknowledged the right of the nation to choose. Consequently the choice on the part of the Lord may have consisted simply in His pointing out to the people, in a very evident manner, the person they were to elect, or in His confirming the choice by word and act, as in accordance with His will.
Three rules are laid down for the king himself in Deu 17:16-20. In the first place, he was not to keep many horses, or lead back the people to Egypt, to multiply horses, because Jehovah had forbidden the people to return thither by that way. The notion of modern critics, that there is an allusion in this prohibition to the constitution of the kingdom under Solomon, is so far from having any foundation, that the reason assigned - namely, the fear lest the king should lead back the people to Egypt from his love of horses, “to the end that he should multiply horses” - really precludes the time of Solomon, inasmuch as the time had then long gone by when any thought could have been entertained of leading back the people to Egypt. But such a reason would be quite in its place in Moses’ time, and only then, “when it would not seem impossible to reunite the broken band, and when the people were ready to express their longing, and even their intention, to return to Egypt on the very slightest occasion; whereas the reason assigned for the prohibition might have furnished Solomon with an excuse for regarding the prohibition itself as merely a temporary one, which was no longer binding” (Oehler in Herzog’s Cyclopaedia: vid., Hengstenberg’s Dissertations).
The second admonition also, that the king was not to take to himself many wives, and turn away his heart (sc., from the Lord), nor greatly multiply to himself silver and gold, can be explained without the hypothesis that there is an allusion to Solomon’s reign, although this king did transgress both commands (1Ki 10:14. Deu 11:1.). A richly furnished harem, and the accumulation of silver and gold, were inseparably connected with the luxury of Oriental monarchs generally; so that the fear was a very natural one, that the future king of Israel might follow the general customs of the heathen in these respects.
