2 Corinthians 10:16

to preach the gospel in the regions beyond you i.e. the rest of Greece, Italy and Spain. Cf. Romans 15:19; Romans 15:24; Romans 15:28. St Paul here attributes his further progress in the Gospel not to his own energy, but to their faith, another instance of his identification of himself with those in whom the same life dwelt. Cf. ch. 2 Corinthians 1:11.

and not to boast in another man's line Literally, and not to have boasted. Both this word and the words translated enlargedand preach the gospelare in the past tense. St Paul here again reflects indirectly, but most severely upon his opponents. Ourhope is first that your faith may increase, and then that we may congratulate ourselves on having carried the good tidings of the Gospel to those who as yet have not heard them, not, as others do, on the successes which by intruding into another man's work, we have found ready made for us.
