Romans 16:10

Ἀπελλῆν τὸν δόκιμον ἐν Χριστῷ : Apelles, that approved Christian. In some conspicuous way the Christian character of Apelles had been tried and found proof: see James 1:12; 2 Timothy 2:15. The name is a familiar one, and sometimes Jewish: Credat Judœus Apella, Hor., Sat., I., v., 100. By τοὺς ἐκ τῶν Ἀριστοβούλου are meant Christians belonging to the household of Aristobulus. Lightfoot, in his essay on Cæsar's Household (Philippians, 171 ff.), makes Aristobulus the grandson of Herod the Great. He was educated in Rome, and probably died there. “Now it seems not improbable, considering the intimate relations between Claudius and Aristobulus, that at the death of the latter his servants, wholly or in part, should be transferred to the palace. In this case they would be designated Aristobuliani, for which I suppose St. Paul's οἱ ἐκ τῶν Ἀριστοβούλου to be an equivalent. It is at least not an obvious phrase, and demands explanation” (Philippians, 175).
