16. Thus says the whole congregation, etc Just as if it had been known that this second altar was opposed to the one only altar of God, they begin with upbraiding them, and that in a very harsh and severe manner. They thus assume it as confessed, that the two tribes had built the altar with a view of offering sacrifices upon it. In this they are mistaken, as it was destined for a different use and purpose. Moreover, had the idea which they had conceived been correct, all the expostulation which they employ would have been just; for it was a clear case of criminal revolt to make any change in the Law of God, who values obedience more than all sacrifices, (1 Samuel 15:22) and there would have been perfect ground for condemning them as apostates, in withdrawing from the one only altar.
