Библейское слово «ἀδελφός» в греческих словарях

I ἀδελφός, эп. ион. ἀδελφε(ι)ός ὁ (voc. ἄδελφε) брат: οἱ ἀδελφοί Eur. etc. братья, реже Eur. брат и сестра; ἀδελφεοὶ ἀπ᾽ ἀμφοτέρων Her. брат и по отцу и по матери.

II ἀδελφός 3

1) братский, братнин (χεῖρες Aesch., Soph.; πολιτεία Plut.);

2) перен. братский, родственный, близкий: ἀδελφὰ τῶνδε и τούτοιν Soph. нечто вроде этого; τούτων ἀδελφά τε καὶ ἀδελφῶν ψυχῶν ἔργα Plat. дела, близкие к этим и совершаемые родственными между собой душами; τῆς ἐν Μαραθῶνι μάχης ἀδελφή Plut. (сражение), напоминающее Марафонское.

ἀδελφός, -οῦ, ὁ
(ἀ- copul., δελφύς, womb),
in cl., a brother, born of the same parent or parents. [In LXX (Hort, Ja., 102f.), for אָח ;]
1. lit. of a brother (Gen.4:2, al.).
2. Of a neighbour (Lev.19:17).
3. Of a member of the same nation (Exo.2:14, Deu.15:3). In NT in each of these senses (1. Mat.1:2, al.; 2. Mat.7:3 3. Rom.9:3) and also,
4. of a fellow-Christian: 1Co.1:1, Act.9:30. This usage finds illustration in π., where ἀ. is used of members of a pagan religious community (M, Th., I, 1:4; MM, VGT, see word). The ἀδελφοὶ τ. Κυρίου (Mat.12:46-49; 13:55; 28:10, Mrk.3:31-34, Luk.8:19-21, Jhn.2:12; 7:3, 5, 10; 20:17, Act.1:14, 1Co.9:5) may have been sons of Joseph and Mary (Mayor, Ja., Intr. viff.; DB, i, 320ff.) or of Joseph by a former marriage (Lft., Gal., 252ff.; DCG, i, 232ff.), but the view of Jerome, which makes ἀ. equivalent to ἀνεψιός, is inconsistent with Greek usage.
