8421.“到第六天”表每个状态的结束。这从“天”和“第六”的含义清楚可知：“天”是指状态（参看23，487，488，493，2788，3462，3785，4850，7680节）；“第六”是指一个状态的结束。“第六”之所以表示一个状态的结束，是因为“七天”或“一周”表示一个完整时期，或一个完整的状态（2044，3845，6508节）；因此，第七天之前的一天，也就是“第六”天，表示这个状态的结束；而接下来的一天，也就是“第八”天表示同一个状态的开始（2044，8400节）。
Potts(1905-1910) 8421
8421. And it shall be in the sixth day. That this signifies in the end of every state, is evident from the signification of "day," as being state (see n. 23, 487, 488, 493, 2788, 3462, 3785, 4850, 7680); and from the signification of "the sixth," as being the end of a state. The reason why "the sixth day" denotes the end of a state is that "seven days" or "a week" signify an entire period, or a full state (n. 2044, 3845, 6508); whence the day preceding the seventh, that is, the sixth day, signifies the end of this state; and the day following, or the eighth day, signifies the beginning of the same state (n. 2044, 8400).
Elliott(1983-1999) 8421
8421. 'And it shall be on the sixth day' means at the end of each state. This is clear from the meaning of 'day' is state, dealt with in 23, 487, 488, 493, 2788, 3462, 3785, 4850, 7680; and from the meaning of 'the sixth' as the end of a state. The reason why 'the sixth day' means the end of a state is that 'seven days' or 'a week' means a whole period or complete state, 2044, 3845, 6508, and therefore the day before the seventh, which is 'the sixth', means the end of that state, while the day after, which is 'the eighth', means the beginning of the same state, 2044, 8400.
Latin(1748-1756) 8421
8421. `Et erit in die sexto': quod significet in fine cujusvis status, constat ex significatione `diei' quod sit status, de qua n. 23, 487, 488, 493, 2788, 3462, 3785, 4850, 7680, et ex significatione `sexti' quod sit finis status; quod `dies sextus' sit finis status, est inde, quia `dies septem' seu (x)`septimana' significat integram periodum seu statum plenum, n. 2044, 3845, 6508, unde dies praecedens {1}septimum seu `sextus' significat finem illius status, et dies sequens seu `octavus' principium ejusdem status, n. 2044, 8400. @1 septimum altered to septimus$
