The right way; the way of truth, 2 Peter 2:2, i.e. the way of faith and holiness, which is the only right way to happiness. Are gone astray; into the by-paths of error. There is but one right way, and many wrong, in which they wander that leave the right. He seems to allude to Balaam, Numbers 22:1-41, who left the way of God, which was, to be obedient to God, and not go beyond his word, Numbers 2:18, and ran into the way of sin, when he went with Balak's messengers to curse God's people; and therefore his way is said to be perverse, Numbers 2:32. Following the way of Balaam;
1. In respect of their false doctrine: for, as Balaam was disobedient to God, and, against his command, went to Balak; so these men forsook the way of truth prescribed by God in his word.
2. In respect of their wicked lives: Balaam taught Balak to entice the children of Israel to commit fornication, and eat things sacrificed unto idols, Revelation 2:14; and these taught men to commit lewdness, and indulge themselves in their sensualities.
3. Chiefly in respect of their covetousness, as follows. Of Bosor; either this is the name of his country, called Pethor, Numbers 22:5, and by change of two letters, P into B, and th into s, (frequent in the Syriac language), Besor, or Bosor: or, the name of his father, called Beor, in Numbers, having two names; unless the apostle call him Bosor in allusion to Basar, flesh, as being of a fleshly mind, as the false teachers here were. Thus Beth-el was called Beth-aven, Hosea 4:15; and Beelzebub called Beelzebul, the god of dung, Matthew 10:25. Who loved the wages of unrighteousness; the reward which Balak offered him for an unrighteous act, viz. the cursing of God's people.
