Is the iniquity of Peor too little for us,.... The worshipping of that idol, when in the plains of Moab; the history of which, see in Num 25:2, was that so small a sin, that another must be added to it, or a greater committed? since building an altar seemed designed not for a single action of idolatrous worship, but for the continuance of it, whereas the sin of Peor was only committed at one time, and not continued in: from which we are not cleansed until this day; not cleared from the shame and disgrace of it, or the guilt of it expiated or removed; but it might be expected, as in the case of the golden calf, that God would still at times punish for it, when provoked by new crimes; or the sense is, that there were those among them that were infected with the same contagion, and whose inclinations were to commit the same, or like sin of idolatry: although there was a plague in congregation of the Lord; of which twenty four thousand died, Num 25:9.
