2 Peter 2:3

And through covetousness;
&c.] Which is generally a prevailing vice among false teachers, they having no other end in view than themselves; either to gain popular applause and vain glory, which they are always covetous of; or to amass riches to themselves, after which they have an insatiable desire:

shall they with feigned words;
made words, words of their own devising, and not which the Holy Ghost teacheth; whereby they cover themselves, and privily introduce their pernicious principles; and therefore new words and phrases are always to be suspected and guarded against, especially in articles of moment and importance: or with flattering words and fair speeches, great swelling words of vanity, having men's persons in admiration, because of worldly advantage; and in this way they gain their point:

make merchandise of you;
deal with the souls of men, as merchants do with their goods, carry them to market and sell them; so false teachers deal with the souls of their followers, draw them, and sell them to Satan, and they themselves pay for it; see ( Zechariah 11:5 ) ( Revelation 18:13 ) but in the issue, and that in a short time, they will be no gainers by such practices:

whose judgment now of a long time lingereth not:
that is, their condemnation, which God in righteousness has determined, "from the creation of the world", as the Ethiopic version reads, or from all eternity, see ( Jude 1:4 ) , to bring them into, for their vile principles and practices, is not retarded and delayed; it does not linger and stay behind, or slacken its pace; it will not tarry, it will come upon them at the appointed time:

and their damnation slumbereth not;
an avenging God, who has appointed them to damnation for their sins, slumbers not; the justice of God is not asleep, nor careless and negligent, but is awake, and watches over them, to bring the evil upon them they have deserved, and is in reserve for them, and will hasten to perform it; the determined destruction does not lie dormant, but in a little time will be stirred up, and fall with dreadful weight on such sinners, as may be concluded from the following awful instances.
