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.

433. That Cain’s being “avenged sevenfold” signifies that it was sacrilege to do violence to that separated faith which is meant by “Cain” has been already shown at verse 15. And that by a “seventy and sevenfold avengement” is signified a far greater sacrilege the consequence of which is damnation, is evident from the signification of “seventy and sevenfold.” That the number “seven” is holy, originates in the fact that the “seventh day” signifies the celestial man, the celestial church, the celestial kingdom, and, in the highest sense, the Lord Himself. Hence the number “seven” wherever it occurs in the Word, signifies what is holy, or most sacred; and this holiness and sanctity is predicated of, or according to, the things that are being treated of. From this comes the signification of the number “seventy” which comprises seven ages; for an age, in the Word, is ten years. When anything most holy or sacred was to be expressed, it was said “seventy-sevenfold” as when the Lord said that a man should forgive his brother not until seven times, but until seventy times seven (Matthew 18:22), by which is meant that they should forgive as many times as he sins, so that the forgiving should be without end, or should be eternal, which is holy. And here, that Lamech should “be avenged seventy and sevenfold” means damnation, because of the violation of that which is most sacred.
