3845. 'Complete this week' means the continuance of the diligent effort. This is clear from the meaning of 'completing' here as serving or completing by serving, and so as meaning diligent effort, dealt with in 3824; and from the meaning of 'a week' as a state and also a whole period, dealt with in 728, 2044, in this case therefore the state and the subsequent period, and so a continuance. What has been said in 3814 about the meaning of 'a month' applies equally to the meaning of 'a week'. When used in the singular 'week' means the end of some previous state and the beginning of the one that follows it, and so a new state; and by the completing of this is meant from its beginning to its end. The reason why 'a week', like every other time-measurement specifically, means a state and also a period of time is that all states also have their own individual periods of the beginning, the continuance, and the end. In the next life however these are not perceived as periods of time but as states and their integral cycles. Here it is quite evident what 'a week' meant to the ancients, namely - in the proper sense - every period that was divided into seven phases, whether it was a period of seven days or of seven years or of seven ages, and so whether it was a long period or a short one. Here it is plainly a period of seven years. And because 'seven' with those people meant that which was holy, see 84-87, 395, 433, 716, 881, 'a week' therefore meant a holy period, and also the holiness of a period.

2044. That 'a son eight days old' means any beginning whatever to purification is clear from the meaning of 'the eighth day'. 'A week', which consists of seven days, means the entire period of any state and length of time - of reformation, regeneration, or temptation, either of the individual in particular or of the Church in general. So the expression 'week' is used whether the period is one of a thousand years, or of a hundred, or of ten, or else one of days, hours, or minutes, and so on, as may become clear from the places quoted in Volume One, in 728. And because the eighth day is the first day of the following week it here means any new beginning whatever. From this it is also clear that just as circumcision itself was a representative of purification, so also was the time when it took place, namely the eighth day. Not that the uncircumcised on that day entered a purer state and on that account were made pure. Rather even as 'circumcision' was a sign meaning purification, so 'the eighth day' meant that such purification ought to go on all the time and so always to be taking place as if from a new beginning.
