 Since it is a Koine Greek "hapax legomenon" found only in the New Testament passages and , its interpretation relies upon morphological analysis and context.The traditional and most common English translation is "daily", although most scholars today reject this in part because all other New Testament passages with the translation "daily" include the word "hemeran" (ἡμέρᾱν, 'day').The difficulty in understanding "epiousios" goes at least as far back as AD 382.
