They have gone astray by abandoning the straight path and have followed the path of Balaam, the son of Bosor, who loved the wages of unrighteousness

Woe to them! For they have traveled in the way of Cain, have abandoned themselves to the error of Balaam for profit, and have perished in Korah’s rebellion.

But I have a few things against you. You have some there who hold to the teaching of Balaam, who taught Balak to place a stumbling block in front of the Israelites: to eat meat sacrificed to idols and to commit sexual immorality.
