And the children of Israel heard say,.... Those that dwelt in the land of Canaan, for otherwise, as before observed, the two tribes and a half on the other side Jordan were Israelites also; and this is a further proof that the altar was built on their side, or those in the land of Canaan would have known of the building of it, and have seen them at it, and not come at the knowledge of it by hearsay only, as it seems they did, it being reported to them by some who had been in those parts, and had seen the structure:

behold, the children of Reuben, and the children of Gad, and the half tribe of Manasseh, have built an altar over against the land of Canaan; which clearly shows it was on the other side Jordan, though Noldius, who places it in the land of Canaan, renders the words, "in the neighbourhood of" it (l); which will not much help him, since it might be in the neighbourhood of it, and yet not in it:

in the borders of Jordan; on the banks of it, or in one of the meanders and windings of it, at a place where it ran out and fetched a compass in the land of Canaan:

at the passage of the children of Israel; where they passed over when they first came into Canaan, and where those tribes also passed over at their return; supposed to be the Bethabara beyond Jordan, where John was baptizing, John 1:28.

(l) "in vicinia", Noldius, No. 369. p. 80.

The Israelites (on this side) heard that the tribes in question had built the altar "opposite to the land of Canaan" (lit. in the face or in front of the land of Canaan), אל־אבר, "at the opposite region of the children of Israel" (two descriptions which may be explained on the supposition that the name of Canaan is used in a restricted sense, the valley of the Jordan being expressly excepted, and Canaan considered as only extending to the valley of the Jordan). When they heard this, the whole congregation (in its heads and representatives) assembled at Shiloh, to go up, i.e., with the intention of going, to make war against them. The congregation supposed that the altar had been built as a place for sacrifice, and therefore regarded it as a wicked violation of the commandment of God with regard to the unity of the sacrificial altar (Leviticus 17:8-9; Deuteronomy 12:4.), which they ought to punish according to the law in Deuteronomy 13:13. This zeal was perfectly justifiable, and even praiseworthy, as the altar, even if not erected as a place for sacrifice, might easily be abused to that purpose, and thus become an occasion of sin to the whole nation. In any case, the two tribes and a half ought not to have erected such a building without the consent of Joshua or of the high priest.

(Note: "We know how sternly the law prohibited the use of two altars: because it was the will of God that His worship should be restricted to one place. When, therefore, from the very appearance it could not fail to occur to the mind of any one that they were establishing a second altar, who would not have condemned them as guilty of sacrilege, for introducing rites and ceremonies at variance with the law of God? And since it might so naturally be regarded as a wicked deed, they ought certainly to have consulted their brethren in so grave and important a matter; and it was especially wrong to pass by the high priest, when the will of God might have been learned from his lips. They were deserving of blame, therefore, because they acted as if they had been alone in the world, and did not consider what offence might easily arise from the novelty of their proceedings." - Calvin.)

And the children of Israel heard say, Behold, the children of Reuben and the children of Gad and the half tribe of Manasseh have built an altar over against the land of Canaan, in the borders of Jordan, at the passage of the children of Israel.

22:11 At the passage - Where they passed over Jordan, either at their first entrance into Canaan, or afterwards, and usually.

Jos 22:11-29. Contention Thereupon.

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 (De 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 (Ex 20:24; Leviticus 17:8, 9; De 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.

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.
