In Revelation 2:14, the church of Pergamum is scolded for tolerating the “teaching of Balaam,” or the “doctrine of Balaam.” Balaam’s name is also invoked in 2 Peter 2:15 and Jude 1:11, both in warnings about the conduct and message of false teachers. All of these are references to the Old Testament character of Balaam, who tried unsuccessfully to prophesy against the people of Israel (Numbers 22). He eventually advised King Balak of Moab, the enemy of Israel, to pursue a campaign of seduction against them (Numbers 31:8.). The doctrine of Balaam is not only a serious problem, but a devious one. When the frontal assault failed, Balaam took a back-door approach.
