Is the iniquity of Peor too little - See this history, Num 25:3 (note), etc., and the notes there. Phinehas takes it for granted that this altar was built in opposition to the altar of God erected by Moses, and that they intended to have a separate service, priesthood, etc., which would be rebellion against God, and bring down his curse on them and their posterity; and, in order to show that God is jealous of his glory, he refers to the business of Baal Peor, which took place in that very country they were now about to possess, the destructive consequences of which he, through his zeal for the glory of God, was the means of preventing.

But that you must turn away this day from following the Lord?.... From the worship of the Lord, as the Targum, and so on Jos 22:16; not content with the former transgression, but must add this revolt unto it, and at a time which sadly aggravates it:

and it will be, that seeing ye rebel to, day against the Lord; against the Word of the Lord, as the Targum, and so on Jos 22:16,

that tomorrow he will be wroth with the whole congregation of Israel; or, in a little time, if a stop is not put to this revolt, the whole body of the people will suffer for it: here they express a concern for the whole nation of Israel, as well as for the glory of God; for sometimes the whole congregation has been charged with the sins of individuals, and punished for it, as a case after mentioned shows; see Jos 7:1.

CONTENTION THEREUPON. (Jos. 22:11-29)

and the children of Israel heard say--Fame speedily spread intelligence of what the trans-jordanic tribes had done. The act being suspected of some idolatrous design, the tribes rose in a mass, and repairing to the tabernacle at Shiloh, resolved to declare war against the two tribes and a half as apostates from God. On calmer and more mature consideration, however, they determined, in the first instance, to send a deputation consisting of the son of the high priest, and ten eminent persons from each tribe, to make inquiry into this rumored rebellion against God (Deu 13:13-15). The quality of the deputies evinced the deep solicitude that was felt on the occasion to maintain the purity of the divine worship throughout Israel. In the presumptive belief that the two tribes and a half had really built an altar, the deputies expressed astonishment at their so soon falling into such a heinous crime as that of violating the unity of divine worship (Exo 20:24; Lev 17:8-9; Deu 12:5-13). They reminded their eastern brethren of the disastrous consequences that were entailed on the nation at large by the apostasy at Peor and by the sin of Achan, and finally exhorted them, if they felt the want of the tabernacle and altar and repented of their rash choice in preferring worldly advantages to religious privileges, to remove to the western side of the Jordan, where all the tribes would form a united and obedient community of worshippers.
