3845. Fulfill this week. That this signifies a further succession of study, is evident from the signification of "fulfilling," as here being to serve or fulfill by serving, thus study (see n. 3824); and from the signification of a "week," as being a state and also an entire period (n. 728, 2044); in the present case therefore a subsequent state and period, consequently what is successive. In regard to the signification of a "week," this is the same as with the signification of a "month" (n. 3814), namely, that when it is mentioned in the singular number, it signifies the end of a former and the beginning of a subsequent state, thus a new state, to "fulfill" which is to proceed from the beginning to the end. The reason why a "week," like all times specifically, signifies a state and also a period, is that all states have also their periods, that is; their beginning, successive progress, and end; yet in the other life these are not perceived as times, but as states and their revolutions. It is here very evident what the ancients understood by a week, namely, in a proper sense, every period that was distinguished into seven, whether it was of days, or of years, or of ages; thus whether it was great or small. That here it is a period of seven years is manifest; and as with the ancients seven signified that which is holy (n. 84-87, 395, 433, 716, 881), a "week" signified a holy period, and also the holiness of a period.
