Moulton & Milligan — Vocabulary of the Greek NT
ἐραυνάω / ἐρευνάω [page 252]
The spelling ἐρευνάω is found ter in the fragmentary P Petr III. 65( b ) .5, .10, .14 (Ptol.), apparently part of a professional searcher s report, but ἐραυνάω , which is adopted throughout by WH, is certain from i/A.D. onwards, e.g. P Oxy II. 294 .9 f. (A.D. 22) (= Selections , p. 35) ὁ ο [ἶκος . . . . .] Σεκόνδας ἠραύνηται κ [αὶ . . . . .] ὁ ἐμ [ὸς ] οἶκος ἠραύνητ [αι : see Proleg. p. 46, where the spelling of the subst. is also discussed. As illustrating the two forms it is enough to cite here P Tebt I. 38 .19 (B.C. 113) ἔρ ]ευναν δὲ τούτου σὺν αὐτοῖς ποιησάμενος , P Oxy I. 67 .18 (A.D. 338) ἐπὶ δυσὶ κεφαλαίοις τὴν ἔραυναν ποιούμενον , making the inquiry concerning two points. MGr ἔρευνα . In P Fay 104 (late iii/A.D.) reference is made ter to ἐραυνηταί , searchers, apparently Customs officials (see the editors note ad .14 ).
