Exhortation takes the form of encouragement, comfort, warning, or strengthening. There is an eschatological urgency to the exhortation which requires an increased activity as the coming of Christ approaches.
Commentary from the MacArthur study Bible, notes for Hebrews 10:25.
Here is the term for robbery. False teachers who are successful in getting people to believe lies, rob them of truth, salvation, and blessing. Far from being advanced, profound knowledge, the false teachers’ beliefs were simplistic and immature like all of the rest of the speculations, ideologies, philosophies, and psychologies the fallen satanic and human system invents.
