2905. A hundred years and twenty years and seven years. That this signifies their fullness, is evident from the signification of a “hundred,” as being what is full (see n. 2636); and of “twenty,” or twice ten, as being also what is full (see n. 1988); and of “seven,” as being what is holy (see n. 395, 433, 716, 881); thus it is the fullness or the end of what is holy belonging to the church that is here signified. (That numbers in the Word all signify things, may be seen above, n. 482, 487, 647, 648, 755, 813, 1963, 1988, 2075, 2252.)

[2] Their fullness, that is, the fullness of the states and times of the church, signifies their end; for the case with the church is like that of the ages of man, of which the first is childhood, the second youth, the third adult age, the fourth old age; the last, or old age, being called the fullness or end. It is also like the times and states of the year; of which the first is spring, the second summer, the third autumn, and the fourth winter; and this last is the end of the year. It is also like the times and states of the day, the first of which is dawn, the second noon, the third evening, and the fourth night; and when this has come, there is fullness or the end. To all these are the states of the church compared in the Word, and they are signified by the same; for by times are signified states (see n. 2625, 2788, 2837).

[3] The good and truth with those who are of the church are wont to decrease in this manner; and when there are no longer any good and truth (or as is said, when there is no longer any faith, that is, no charity) then the church has come to its old age, or its winter, or its night; and its time and state then are called “decision,” “consummation,” and “fulfillment” (see n. 1857). The same is signified when it is said of the Lord that He came into the world in the fullness of times, or when there was fullness; for there was then no longer any good, not even natural good; and consequently there was no truth. These are the things specifically signified by what is said in this verse.

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.
