4123. A way of seven days. That this signifies the holy of truth, is evident from the signification of a “way,” as being truth (n. 627, 2333); and from the signification of “seven,” as being what is holy (n. 395, 433, 716, 881). Here the signification is that there was the ardor of conjunction, that is, of conjoining itself with the holy of truth.

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.
