The story of a prophet who wanted to be a prophet and also be rich.  Gods warnings to him and mercy to him and Balaam's ultimate choice -- you cannot serve God and Wealth.  Balaam tried to do it both ways.

 "forsaking the right way, they have gone astray, having followed the way of Balaam, the son of Beor, who loved the wages of unrighteousness;" 2 Peter 2:15

"they have rushed headlong into the error of Balaam." Jude 1:11

"But I have a few things against you, because you have there some who hold the teaching of Balaam, who kept teaching Balak to put a stumbling block before the sons of Israel, to eat things sacrificed to idols and to commit acts of immorality." Revelation 2:14

“No one can serve two masters; for either he will hate the one and love the other, or he will be devoted to one and despise the other. You cannot serve God and wealth." Matthew 6:24
