Jamieson, Fausset & Brown, on Jude 1:11

“Woe unto them, for they have gone in the way of Cain: and after the error of Balaam they have for reward poured out themselves, and have perished in the contradiction of Core.”

“Woe--See on Pe2 2:14, "cursed children." Cain--the murderer: the root of whose sin was hatred and envy of the godly, as it is the sin of these seducers. ran greedily--literally, "have been poured forth" like a torrent that has burst its banks. Reckless of what it costs, the loss of God's favor and heaven, on they rush after gain like Balaam. perished in the gainsaying of Core--(compare Note, see on Jde 1:12). When we read of Korah perishing by gainsaying, we read virtually also of these perishing in like manner through the same: for the same seed bears the same harvest.”
