We stretch not ourselves beyond our measure (μὴ ὑπερεκτείνομεν ἑαυτούς)
The verb only here in the New Testament. The A.V. is needlessly verbose. Rev., better, stretch not ourselves overmuch.
As though we reached not unto you
Lit., as not reaching. Paul would say: It is not as if God had not appointed our apostolic labor to reach to you. If He had not thus appointed, then our desire to labor among you would have been an overstretching of ourselves. Therefore, in boasting of our labor in Corinth, we do not boast beyond our measure.
We are come (ἐφθάσαμεν)
Rev., we came. The verb originally means to come before, anticipate, as 1Th 4:15 (A.V., prevent; Rev., precede); but it gradually loses the idea of priority, and means simply come to, arrive at. So Mat 12:28; Phi 3:16. It may possibly be used here with a hint of the earlier meaning, were the first to come. See Rev., margin.
