3824. And he said, I will serve thee seven years for Rachel thy younger daughter. That this signifies study, and at the same time a holy state, in order to be conjoined with internal truth, is evident from the signification of “serving,” as being study; and from the signification of “seven,” as being that which is holy (see n. 395, 433, 716, 881); and from the signification of “years,” as being states (n. 487, 488, 493, 893); that this was in order to conjunction is evident. Hence it is manifest that by “I will serve thee seven years for Rachel thy younger daughter,” signifies study, and at the same time a holy state in order to be conjoined with internal truth. Internal truths are said to be conjoined with the natural when they are learned, acknowledged, and believed. In the natural of man, that is, in the memory of this man, there are truths both external and internal, and they are there in the form of memorized doctrinal things; but they have not been conjoined until the man is affected with them for the sake of the use of life, that is, until they are loved for the sake of life; for then good is coupled with them, whereby they are conjoined with the rational, consequently with the internal man. In this way there is an influx of life into them from the Lord.

493. That by “days” and “years” are signified times and states needs no further explication, except to say that in the world there must needs be times and measures, to which numbers may be applied because they are in the ultimates of nature; but whenever they are applied in the Word, the numbers of the days and years, and also of the measures, have a signification abstractedly from the times and measures, in accordance with the signification of the number; as where it is said that there are six days of labor, and that the seventh is holy, of which above; that the jubilee should be proclaimed every forty-ninth year, and should be celebrated in the fiftieth; that the tribes of Israel were twelve, and the apostles of the Lord the same; that there were seventy elders, and as many disciples of the Lord; and so in many other instances where the numbers have a special signification abstractedly from the things to which they are applied; and when thus abstracted, then it is states that are signified by the numbers.
