Show them the manner of the king - The word משפט mishpat, which we here render manner, signifies simply what the king would and might require, according to the manner in which kings in general ruled; all of whom, in those times, were absolute and despotic.
The whole of this manner of the king is well illustrated by Puffendorf.
"Hitherto," says he, "the people of Israel had lived under governors raised up of God, who had exacted no tribute of them, nor put them to any charge; but, little content with this form of government. they desire to have a king like other nations, who should live in magnificence and pomp, keep armies, and be able to resist any invasion. Samuel informs them what it was they desired; that when they understood it, they might consider whether they would persist in their choice If they would have a king splendidly attended, he tells them that he would take their sons for his chariots, etc.; if they would have him keep up constant forces, then he would appoint them for colonels and captains, and employ those in his wars who were accustomed to follow their family business; and since, after the manner of other kings, he must keep a stately court, they must be content that their daughters should serve in several offices, which the king would think below the dignity of his wives and daughters, 1 Samuel 8:13. Many ministers also, in several departments, both of war and peace, must have salaries to support them, which must be paid out of their fields and vineyards, 1 Samuel 8:14. In one word, that to sustain his dignity their king would exact the tenth of all they possessed, and be maintained in a royal manner out of their estates."
It is perfectly vain in Grotius, or any one else, to state that this shows what a king, as king, may any where in virtue of his office, claim and exact; and that he can take the property and persons of his subjects, and dispose of them as he may judge necessary for the exigence of the state. This was the manner of Saul, but Saul was not a king of God's choosing: "He gave him in his wrath, and took him away in his displeasure;" and the manner of such a king should not be arrogated by any potentate who affects to rule jure divino, by Divine right. The manner of the king of God's choice is distinctly detailed, Deuteronomy 17:15-20, to which the reader will do well to refer, that he may have an impartial statement of the subject.
