Lexicographers agree on the range of this verb. BDAG gives the active "to cause pain" (not attested in the New Testament) and organizes the middle-passive as "to experience physical pain or mental anguish, suffer pain, be in agony" (Luke 2:48; 16:24, 25), with a distinct construction using ἐπί plus the dative, "to be extremely distressed about someone or something" (Acts 20:38). LSJ likewise gives "cause one pain, either of body or of mind" and, in the middle-passive, "suffer pain, be grieved, be distressed," documenting both senses side by side from the earliest attestations in Aristophanes, Sophocles, Plato, and the Hippocratic corpus. Louw and Nida split the four occurrences across two semantic domains: great pain (Luke 16:24-25) and severe emotional distress (Luke 2:48; Acts 20:38); Thayer distinguished the shades by voice. EDNT and Moulton-Milligan confirm that the word was ordinary Koine, at home in private letters of consolation and inquiry about missing relatives. The verb is built on the noun ὀδύνη ("pain, distress"), which appears twice in the New Testament, both in Paul (Romans 9:2; 1 Timothy 6:10). In the Greek Old Testament the verb and noun render a wide spread of Hebrew pain, grief, and labor-pang terms (including חוּל, מָרַר, דָּוָה, כָּאַב, and יָגוֹן), and the cognate-accusative construction of Zechariah 12:10 (mourning "as for a firstborn") lies behind the tradition of mourning over the pierced one. Commentators are unanimous on the contextual applications: acute emotional anxiety in Luke 2:48 (Fitzmyer, Marshall, Bock, Nolland, Bovon), comprehensive torment of body and mind in the parable of the rich man and Lazarus, where the reversal pair "is comforted" and "are in torment" forms the rhetorical hinge of Luke 16:25 (Fitzmyer, Bock, Bovon), and intense grief in the farewell scene at Miletus in Acts 20:38 (Barrett, Keener, Pervo, Witherington). Every commentator notes that the verb is confined to Luke and Acts and treats it as one of Luke's stylistic fingerprints in the vocabulary of pathos. The best-known scholarly claim about the word concerns authorship rather than meaning: W. K. Hobart (1882) listed it among the terms supposedly betraying Luke's medical training, but Henry Cadbury (1919-1920) showed that the same method applied to Lucian would "prove" Lucian a physician too, and the consensus since has treated the word as common Greek whose clustering in medical writers reflects only how often those writers discuss pain. Digital-corpus work by Luuk van de Weghe (2025) has statistically re-listed the verb among terms that favor medical corpora, though he concedes that Lukan and Lucianic "medical" vocabulary remain comparable in number, so Cadbury's counterexample still holds.
