For this cause I also, when I couldn't stand it any longer, sent that I might know your faith, for fear that by any means the tempter had tempted you, and our labor would have been in vain.
And our labour be in vain: in preaching the Gospel among them; not with respect to God, to whom the word never returns void and empty; nor with regard to the apostles, whose judgment was with the Lord, and their work with their God, who will of his own grace reward them; but with respect to the Thessalonians, to whom, should Satan gain his point, it would be of no use and service, for which the concern was. The Ethiopic version reads, "and your labour be in vain": in receiving the apostles, embracing and professing the Gospel, and suffering for it; see Galatians 3:4 but the common reading is best, and agrees with what the apostle elsewhere says, Galatians 4:11.
