2 Peter 2:15-17

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; but was rebuked for his iniquity: the dumb ass speaking with man's voice forbad the madness of the prophet. These are wells without water, clouds that are carried with a tempest; to whom the mist of darkness is reserved for ever.
