Deuteronomy 27:11

With the solemn erection of the stones with the law written upon them, Israel was to transfer to the land the blessing and curse of the law, as was already commanded in Deu 11:29; that is to say, according to the more minute explanation of the command which is given here, the people themselves were solemnly to give expression to the blessing and the curse: to the former upon Mount Gerizim, and to the latter upon Ebal. On the situation of these mountains, see at Deu 11:29. To this end six tribes were to station themselves upon the top or side of Gerizim, and six upon the top or side of Ebal. The blessing was to be uttered by the tribes of Simeon, Levi, Judah, Issachar, Joseph, and Benjamin, who sprang from the two wives of Jacob; and the curse by Reuben, with the two sons of Leah's maid Zilpah, and by Zebulun, with Dan and Naphtali, the sons of Rachel's maid Bilhah. It was natural that the utterance of the blessing should be assigned to the tribes which sprang from Jacob's proper wives, since the sons of the wives occupied a higher position than the sons of the maids - just as the blessing had pre-eminence over the curse. But in order to secure the division into two sixes, it was necessary that two of the eight sons of the wives should be associated with those who pronounced the curses. The choice fell upon Reuben, because he had forfeited his right of primogeniture by his incest (Gen 49:4), and upon Zebulun, as the youngest son of Leah. "They shall stand there upon the curse:" i.e., to pronounce the curse.

When the law was written, to be seen and read by all men, the sanctions of it were to be published, which, to complete the solemnity of their covenanting with God, they were deliberately to declare their approbation of. This they were before directed to do (Deu 11:29, Deu 11:30), and therefore the appointment here begins somewhat abruptly, Deu 27:12. There were, it seems, in Canaan, that part of it which afterwards fell to the lot of Ephraim (Joshua's tribe), two mountains that lay near together, with a valley between, one called Gerizim and the other Ebal. On the sides of these two mountains, which faced one another, all the tribes were to be drawn up, six on one side and six on the other, so that in the valley, at the foot of each mountain, they came pretty near together, so near as that the priests standing betwixt them might be heard by those that were next them on both sides; then when silence was proclaimed, and attention commanded, one of the priests, or perhaps more at some distance from each other, pronounced with a loud voice one of the curses here following, and all the people that stood on the side and foot of Mount Ebal (those that stood further off taking the signal from those that stood nearer and within hearing) said Amen; then the contrary blessing was pronounced, "Blessed is he that doth not so or so," and then those that stood on the side, and at the foot, of Mount Gerizim, said Amen. This could not but affect them very much with the blessings and curses, the promises and threatenings, of the law, and not only acquaint all the people with them, but teach them to apply them to themselves. I. Something is to be observed, in general, concerning this solemnity, which was to be done, but once and not repeated, but would be talked of to posterity,. 1. God a…
