A.T. Robertson Commentary 2 Corinthians 10:14

"For we stretch not ourselves overmuch, as though we reached not unto you: for we came even as far as unto you in the gospel of Christ:" — 2 Corinthians 10:14 (ASV)

We stretch not ourselves overmuch (ου υπερεκτεινομεν εαυτους). Apparently Paul made this double compound verb to express his full meaning (only in Gregory Nazianzen afterwards). "We do not stretch ourselves out beyond our rights."

We came even as far as unto you (αχρ κα υμων εφθασαμεν). First aorist active indicative of φθανω, to come before, to precede, the original idea which is retained in Mt 12:28 (Luke 11:20) and may be so here. If so, it means "We were the first to come to you" (which is true, Acts 18:1–18).
