“Which have forsaken the right way, and are gone astray, following the way of Balaam the son of Bosor, who loved the wages of unrighteousness;”
King James Version (KJV)
2:15 The way of Balaam the son of Bosor - So the Chaldeans pronounced what the Jews termed Beor; namely, the way of covetousness. Who loved - Earnestly desired, though he did not dare to take, the reward of unrighteousness - The money which Balak would have given him for cursing Israel.
2Pe 2:15 Following the way of Balaam. See Nu 31:16. Balaam sold himself out to an evil cause for the sake of gain.
