1 Samuel 10:17

Samuel called the people together. — “Samuel does all that further lies in his power to promote the great cause. He calls a national assembly to Mizpeh. Here the sacred lot, it is stated, fell, among all the tribes of Israel, upon Benjamin; and, in an ever narrowing circle, at length upon Saul, the son of Kish. If we consider the general use in those ages of the sacred lot, we shall find that, taking the whole account in this connection, it exhibits nothing but the great truth that for the full and auspicious acknowledgment of Saul as king, his mysterious interview with the seer did not alone suffice — publicly, in solemn national assembly, was it necessary for the Spirit of the Eternal to choose him out, and to make him known as the Eternal’s man.” — Ewald.

Mizpah (for so the name should be spelt) was chosen by Samuel for the solemn assembly of the tribes on the occasion of the electing their first king, on account of the glorious memories of his own victory, many years before, at that place. The words, “unto the Lord” probably signify that the mysterious Urim and Thummim, by which inquiry was used to be made of the Eternal, had been brought there by the high priest, or, on the supposition that the office was then vacant, by the priest who temporarily replaced him.
