(20) **For if after they have escaped the pollutions of the world.**—Applying the general statement of the preceding verse to the case of these false teachers. In the *Shepherd* of Hermas (I. *Vis.* IV. iii. 2.) “the black there is the world in which we dwell, and the fire-and-blood-colour (indicates) that this world must perish through blood and fire; but the golden part are ye *who have escaped this world.”* Another *possible* reminiscence of our Epistle. (See above on 2Peter 2:1; 2Peter 3:13; 2Peter 3:15; and below, 2Peter 3:5.)
**Through the knowledge.**—Better, *in knowledge* the preposition “in” pointing to that in which the escape consists. (See on 2Peter 2:18, and comp. Luke 1:77.) The knowledge is of the same mature and complete kind as that spoken of in 2Peter 1:2-3; 2Peter 1:8 (where see Notes), showing that these *men* were well-instructed Christians.
**Entangled therein, and overcome.**—Or, *entangled and overcome thereby, *which, from the latter part of 2Peter 2:19, seems to be the more probable construction.
**The latter end is worse with them than the beginning.**—Most certainly this should be made to correspond with Matthew 12:45, of which it is almost an exact reproduction—*their last state is worse than the first.* The only difference is that the word for “is” in Matthew 12:45 means literally “becomes,” and here “has become.” (Comp. the *Shepherd, Sim.* IX. xvii. 5.)
