2 Thessalonians 2:17 - Ellicott's Commentary On The Whole Bible

Comfort your hearts... — “Comfort,” in reference to the “unending comfort” of 2 Thessalonians 2:16; and “stablish,” in reference to the “good hope in grace.” The “heart” needs comfort as the seat of emotions. “In every good word and work” (it should be, work and word) means in the maintenance of every good doctrine (as opposed to the false teaching which had got abroad about the Advent, and to the lies of the Apostasy), and in the performance of every good practice (as opposed to the lawlessness of the Apostasy, and to the disorderly conduct of which the next chapter treats: for here, as in 1 Thessalonians 3:13, the prayer forms an introduction of the next subject). The singular number of the verbs “comfort” and “stablish” (which, of course, does not appear in the English), may perhaps be explained as in 1 Thessalonians 3:12, where see Note, though it is not necessary so to understand it, inasmuch as the intervening relative (in the Greek, participial) clauses have turned the whole attention to the Father, who may be considered exclusively as the grammatical subject of the verbs. It would, however, have been painful to orthodox ears; however justifiable doctrinally, to have used a plural verb. It is by these little incidental touches, still more than by express doctrinal statements, that we learn what was the real belief of the Apostles concerning the Divinity of Christ; and we may say the same with regard to many other great doctrines.
