“But I have a few things against thee, because thou hast there them that hold the doctrine of Balaam, who taught Balac to cast a stumblingblock before the children of Israel, to eat things sacrificed unto idols, and to commit fornication.”
King James Version (KJV)
2:14 But thou hast there - Whom thou oughtest to have immediately cast out from the flock. Them that hold the doctrine of Balaam - Doctrine nearly resembling his. Who taught Balak - And the rest of the Moabites. To cast a stumblingblock before the sons of Israel - They are generally termed, the children, but here, the sons, of Israel, in opposition to the daughters of Moab, by whom Balaam enticed them to fornication and idolatry. To eat things sacrificed to idols - Which, in so idolatrous a city as Pergamos, was in the highest degree hurtful to Christianity. And to commit fornication - Which was constantly joined with the idol - worship of the heathens.
Re 2:14 But I have a few things against thee. Much as been to the credit of the church, but there is another side. Them that hold the doctrine of Balaam. Teachers like Balaam who seduce the true Israel into sin. Balaam showed Balak how to lead the children of Israel astray. See Nu 25:2 31:16. In the same way there were false teachers at Pergamos who taught that Christians might join the idol feasts and in heathen fornication.
