“Woe unto them! for they have gone in the way of Cain, and ran greedily after the error of Balaam for reward, and perished in the gainsaying of Core.”
King James Version (KJV)
1:11 Woe unto them - Of all the apostles St. Jude alone, and that in this single place, denounces a woe. St. Peter, to the same effect, pronounces them cursed children. For they have gone in the way of Cain - The murderer. And ran greedily - Literally, have been poured out, like a torrent without banks. After the error of Balaam - The covetous false prophet. And perished in the gainsaying of Korah - Vengeance has overtaken them as it did Korah, rising up against those whom God had sent.
Jude 1:11 Woe unto them! The denunciation of woes, common in the Lord's ministry, is only found here in all the rest of the New Testament. For they have gone in the way of Cain. Living selfish lives, full of hate. And ran greedily after the error of Balaam for reward. Like Balaam trying to make a gain of godliness. See notes on "2Pe 2:15". Perished in the gainsaying of Korah. Like Balaam they are false prophets. Like Korah, who profanely thrust himself into the priesthood and perished, they intrude irreverently into holy places.
