ἡμέρα
hēméra
hay-mer'-ah
feminine (with ὥρα implied) of a derivative of a Greek word not found in the New Testament (to sit; akin to the base of ἑδραῖος) meaning tame, i.e. gentle; day, i.e. (literally) the time space between dawn and dark, or the whole 24 hours (but several days were usually reckoned by the Jews as inclusive of the parts of both extremes); figuratively, a period (always defined more or less clearly by the context).

KJV translates as: age, + alway, (mid)day (by day, (ly)), + for ever, judgment, (day) time, while, years
