eight cardinal number, where there are eight instances of a countable entity To designate a week, the normal practice in NT times was to speak of ‘eight days,’ since in a series both the first and the last days were counted. The equivalent in many languages would be simply ‘after seven days had passed’ (LUK 2:21).
