And indeed ye do it — i.e., “love one another;” but the words seem to imply a very practical form of love. This fact justifies St. Paul in saying that the Thessalonians were so taught of God.
Toward. — Rather, even unto; as far as unto. The Thessalonians’ charity has travelled already a long way from its starting-point at home, extending over all northern Greece. As Thessalonica had been the centre of evangelisation (1 Thessalonians 1:8), so also of the maintenance of the Churches. The words need not necessarily (though they do probably) imply a number of missionary stations besides the three places where the Apostles had preached.
Increase more and more. — A little too emphatic: abound (or, overflow) still more. The words are identical with those in 1 Thessalonians 4:1. The brotherly kindness of the Thessalonians did not spread over a wide enough area in merely traversing Macedonia, nor was it so unostentatious as true love should be.
