an adjective, signifying an "eighth-day" person or thing, "eight days old" (okto, and hemera, "a day"), is used in Philippians 3:5. This, and similar numerical adjectives not found in the NT, indicate duration rather than intervals. The Apostle shows by his being an "eighth-day" person as to circumcision, that his parents were neither Ishmaelites (circumcised in their thirteenth year) nor other Gentiles, converted to Judaism (circumcised on becoming Jews).
