Verse 18. - But that ye must turn. The original has the imperfect, of an action not completed, "and ye are turning." There is no need to give the adversative sense to! The ye also is emphatic. "Ye are turning against the Lord today, tomorrow ye will involve the whole congregation in calamity." That tomorrow he will be wroth with the whole congregation of Israel. This passage also is quite consistent with the circumstances and with the position of the speaker. Not merely anger but fear is visible throughout - fear of His wrath who had manifested His power so signally of late. There was no longer any temptation to rebel against Him. The Israelites were no longer suffering the daily pressure of comparative privation and distress, such as it was impossible to avoid in the wilderness. While, on the contrary, there was every reason to remember His power Who had driven the heathen out before them and planted them in, Who had not failed to punish them when they deserved it, and Who, by the fate of their enemies, had made it clear that His hands were not waxen short. Thus the heads of the tribes, and Phinehas especially, were alarmed lest Israel should forfeit the prosperity they at present enjoyed, and exchange it for those terrible woes that God had shown He could inflict when His people rebelled against Him.

22:10-20 Here is the care of the separated tribes to keep their hold of Canaan's religion. At first sight it seemed a design to set up an altar against the altar at Shiloh. God is jealous for his own institutions; we should be so too, and afraid of every thing that looks like, or leads to idolatry. Corruptions in religion are best dealt with at first. But their prudence in following up this zealous resolution is no less commendable. Many an unhappy strife would be prevented, or soon made up, by inquiries into the matter of the offence. The remembrance of great sins committed formerly, should engage us to stand on our guard against the beginnings of sin; for the way of sin is down-hill. We are all concerned to reprove our neighbour when he does amiss, lest we suffer sin upon him, Le 19:17. The offer made that they should be welcome to come to the land where the Lord's tabernacle was, and settle there, was in the spirit of true Israelites.But that you must turn away this day from following the Lord?.... From the worship of the Lord, as the Targum, and so on Joshua 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 Joshua 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 Joshua 7:1.
