These shall stand upon mount Gerizim to bless the people, when ye are come over Jordan; Simeon, and Levi, and Judah, and Issachar, and {f} Joseph, and Benjamin:

(f) Meaning, Ephraim and Manasseh.

Wesley's Notes

27:12 Upon mount Gerizzim - These words may be rendered beside or near to mount Gerizzim. There were in Canaan two mountains that lay near together, with a valley between, one called Gerizzim, the other Ebal. On the sides of these which faced each other, all the tribes were to be drawn up, six on a side, so that in the valley they came near each other, so near that the priests standing between them, might be heard by them that were next them on both sides. Then one of the priests, or perhaps more, at some distance from each other, pronounced with a loud voice, one of the curses following. And all the people who stood on the foot and side of mount Ebal, (those farther off taking the signal from those who were nearer) said Amen! Then the contrary blessing was pronounced, Blessed is he that doth so or so: To which all who stood on the foot and side of mount Gerizzim, said, Amen! Simeon - All these were the children of the free - women, Leah and Rachel, to shew both the dignity of the blessings above the curses, and that the blessings belong only to those who are evangelically such, as this is expounded and applied, Gal 4:22, even to those that receive the Spirit of adoption and liberty. Joseph is here put for both his sons and tribes Manasseh and Ephraim, which are reckoned as one tribe, because Levi is here numbered; but when Levi is omitted, as it is where the division of the land is made, there Manasseh and Ephraim pass for two tribes.

Matthew Henry's Concise Commentary

27:11-26 The six tribes appointed for blessing, were all children of the free women, for to such the promise belongs, Ga 4:31. Levi is here among the rest. Ministers should apply to themselves the blessing and curse they preach to others, and by faith set their own Amen to it. And they must not only allure people to their duty with the promises of a blessing, but awe them with the threatenings of a curse, by declaring that a curse would be upon those who do such things. To each of the curses the people were to say, Amen. It professed their faith, that these, and the like curses, were real declarations of the wrath of God against the ungodliness and unrighteousness of men, not one jot of which shall fall to the ground. It was acknowledging the equity of these curses. Those who do such things deserve to fall, and lie under the curse. Lest those who were guilty of other sins, not here mentioned, should think themselves safe from the curse, the last reaches all. Not only those who do the evil which the law forbids, but those also who omit the good which the law requires. Without the atoning blood of Christ, sinners can neither have communion with a holy God, nor do any thing acceptable to him; his righteous law condemns every one who, at any time, or in any thing, transgresses it. Under its awful curse we remain as transgressors, until the redemption of Christ is applied to our hearts. Wherever the grace of God brings salvation, it teaches the believer to deny ungodliness and wordly lusts, to live soberly, righteously, and godly in this present world, consenting to, and delighting in the words of God's law, after the inward man. In this holy walk, true peace and solid joy are to be found.
