(11) Have built an altar.--Rather, have built the altar. As appears by Joshua 22:28, it was a representation of the altar of Jehovah: a copy of the one altar which He had given to Israel for sacrifice. The design was to set up on the east of Jordan a likeness of that altar which was established on the west, that the tribes on the other side of Jordan might appeal to it as a proof that they also were the people of Jehovah.

Verse 11. - Half tribe of Manasseh. Throughout this part of the narrative, when the body politic, rather than the descent of the tribe, is to be indicated, we have, not מַטֶּה, but שֶׁבֶט. See above, Joshua 13:29. An altar. The original has the altar. Over against אֶל־מוּל. It is difficult to fix the meaning of this expression. מוּל seems to have meant the front of anything, and therefore אֶל־מוּל would naturally mean towards the front of, or in front cf. Thus we have had the expression in Joshua 8:33 (where see note), where it seems to mean, in the direction of, and in Joshua 9:1, where it seems to have the same meaning. With verbs of motion it signifies towards, as in Exodus 34:3, and 1 Samuel 17:30. Here it clearly cannot be pressed to mean across Jordan. See note below. The borders of Jordan. As above, ver. 10, the circles of Jordan. At the passage of the children of Israel. The word translated "the passage of," literally," unto over," has originally the sense of "across." Here, however, it means "towards the region opposite to the sons of Israel," i.e., in the direction of the country on the other side Jordan. The country across Jordan was usually designated as בְּעֵבֶר or מֵעֵבֶר Jordan. אֶל־עֵבֶר, the phrase used here, we find in Exodus 28:26, apparently in the sense of across (so Exodus 39:19). In Deuteronomy 30:13 it is used of moving in the direction of a place, "across" or "over the sea." In Ezekiel 1:9, 12, with the addition of פָנָיו, the phrase means "straight forward." In 1 Samuel 14:40 לְעֵבֶר אֶהַד means "on one side." In 1 Kings 7. לְעֵבֶר means "over." Thus the altar was not necessarily on the other side Jordan.

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.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.
