2 Pedro 2:2

And many shall follow their pernicious ways; Greek, their destructions, i.e. those ways of error which are attended with destruction (the effect being put for the cause by a metonymy); and the sense is, that as these false teachers shall bring destruction upon themselves by their heresies; so others, running with them into the same errors, shall fall into the same destruction.

By reason of whom; or, by whom, viz. these false teachers, or their followers, or both.

The way of truth; the gospel, so called, as being the doctrine of saving truth. It is called the way, Acts 9:2; Acts 19:9; Acts 22:4; the way of salvation, Acts 16:17; the way of God, Acts 18:26.

Shall be evil spoken of; blasphemed, whether by false teachers themselves and their followers, or by others taking occasion by them: see Romans 2:24; 1 Timothy 6:1; Titus 2:5.
