Greatly (lian). Only here and 3 John 1:3 in John's writings. I have found (eurhka). Perfect active indicative of euriskw as in John 1:41 , our "eureka," here with its usual force, a continued discovery. "He sits down at once and writes to Kyria. How glad she would be that her lads, far away in the great city, were true to their early faith" (David Smith). Certain of thy children (ek twn teknwn). No tina as one would expect before ek, a not infrequent idiom in the N.T. ( John 16:17 ). Walking (peripatounta). Present active accusative supplementary participle agreeing with tina understood. Probably members of the church off here in Ephesus. In truth (en alhqeiai). As in verse John 1 ; 3 John 1:4 . We received (elabomen). Second aorist active (possibly, though not certainly, literary plural) of lambanw. This very idiom (entolhn lambanw) in John 10:18 ; Acts 17:15 ; 4:10 .
