4670. A son of seventeen years. That this signifies its state, is evident from the years of the ages of those mentioned in the Word, in that like other numbers they signify things and states. (That all numbers in the Word signify things and states may be seen above, n. 575, 647, 648, 1988, 2075, 2252, 3252, 4264, 4495; as also years, n. 487, 488, 493, 893)

[2] It indeed appears as if numbers of years, or years of ages, had no further meaning, because they seem to be more historical than other numbers. But that these also involve things and states is evident from what was unfolded in the fifth chapter of Genesis, and said as to the age of Abraham (Genesis 17:1; 25:7), and that of Isaac (Genesis 35:28); and moreover from the fact that there is no historical statement in the Word which does not involve what is heavenly; into which also it is changed when it passes from the thought of the man who is reading, to the angels with him, and through the angels to heaven, where from every historical of the Word a spiritual sense is produced.

[3] But what is signified by Joseph’s age of seventeen years may be seen from the signification of this number in other places, namely, a beginning, but here the beginning of the representation by Joseph. (That this number signifies a beginning and what is new, may be seen above, n. 755, 853.) Moreover in a general and potential way this number involves all that is represented by Joseph; for “seven” signifies holy, and “ten,” remains. (That “seven” in the Word adds holiness may be seen above, n. 881; and that “ten” denotes remains, n. 576, 1906, 2284.) That the remains in the Lord by means of which He united the Human essence to the Divine, were Divine and of Himself, may be seen above (n. 1906).

575. That by the days of man being a hundred and twenty years is signified that he ought to have remains of faith, appears from what has been said in the foregoing chapter (Genesis 5:3-4), concerning “days” and “years” signifying times and states; and also from the circumstance of the most ancient people from numbers variously compounded signifying states and changes of states in the church; but the nature of their ecclesiastical computation is now totally lost. Here in like manner numbers of years are mentioned, whose signification it is impossible for anyone to understand, unless he be first acquainted with the hidden meaning of each particular number from “one” to “twelve” and so on. It plainly appears that they contain within them something else that is secret, for that men were to live a “hundred and twenty years” has no connection with the preceding part of the verse, nor did they live one hundred and twenty years, as is evident from the people after the flood (chapter 11), where it is said of Shem that “he lived after he begat Arphaxad five hundred years;” and that Arphaxad lived after be begat Selah “four hundred and three years;” and that Selah lived after he begat Eber “four hundred and three years;” and that Eber lived after he begat Peleg “four hundred and thirty years;” and that Noah lived after the flood “three hundred and fifty years” (Genesis 9:28), and so on. But what is involved in the number “one hundred and twenty” appears only from the meaning of “ten” and “twelve” which being multiplied together make one hundred and twenty, and from the signification of these component numbers it may be seen that “one hundred and twenty” signifies the remains of faith. The number “ten” in the Word, as also “tenths” signify and represent remains, which are preserved by the Lord in the internal man, and which are holy, because they are of the Lord alone; and the number “twelve” signifies faith, or all things relating to faith in one complex; the number therefore that is compounded of these, signifies the remains of faith.
