Ἑβραῖος (G1445)
4 † Ἑβραῖος (WH, Ἐβ- ), -α, -ον (Aram, עִבְרַי ), as subst. , ὁ Ἑ. , [in LXX for עֵבֶר , עִבְרִי ;] a Hebrew . In OT, of Israelites in contrast with those of another race ( Ge 14:13 , Ex 1:15 , De 15:12 , al.). In NT as the correlative of Ἑλληνιστής , a Jew who had adopted, in greater or less degree, Greek culture and Greek language. The distinction was not merely linguistic ( DB , ii, 325); as far as it was so, Συριστής would be a more correct Greek term for the Jew of Semitic speech (v.s. Ἑβραΐς , and cf. Dalman, Words , 7): Ac 6:1 , II Co 11:22 , Phl 3:5 .†
