Adam Clarke on 1 Samuel 2:18

Girded with a linen ephod - This the Targum translates אסיר כרדוט דבוץ asir cardut debuts, "Girded with a cardit of byssus, or fine linen." The word cardut they seem to have borrowed from the Greek χειριδωτος, a tunic, having χειριδας, i.e., sleeves that came down to, or covered, the hands. This was esteemed an effeminate garment among the Romans. See Buxtorf's Talmudic Lexicon.
