The separate tribes were gratified, and, since they had a mind to preserve among them this pattern of the altar of God, though there was not likely to be that occasion for it which they fancied, yet Joshua and the princes let them have their humour, and did not give orders for the demolishing of it, though there was as much reason to fear that it might in process of time be an occasion of idolatry as there was to hope that ever it might be a preservation from idolatry. Thus did the strong bear the infirmities of the weak. Only care was taken that they having explained the meaning of their altar, that it was intended for no more than a testimony of their communion with the altar at Shiloh, this explanation should be recorded, which was done according to the usage of those times by giving a name to it signifying so much (v. 34); they called it Ed, a witness to that, and no more, a witness of the relation they stood in to God and Israel, and of their concurrence with the rest of the tribes in the same common faith, that Jehovah he is God, he and no other. It was a witness to posterity of their care to transmit their religion pure and entire to them, and would be a witness against them if ever they should forsake God and turn from following after him.
