3016. Abraham being old was come into days. That this signifies when the state was at hand that the Lord’s Human should be made Divine, is evident from the representation of Abraham, as being the Lord (see n. 1893, 1965, 1989, 2011, 2172, 2198, 2501, 2833, 2836, and many other places); and from the signification of “old,” or of “old age,” as being to put off what is human, and put on what is heavenly (see n. 1854, 2198); and when predicated of the Lord, as being to put on the Divine. The same is evident also from the signification of “day,” as being state (see n. 23, 487, 488, 493, 893, 2788); and hence from the signification of “coming into days,” as being when the state was at hand. Such things are signified by “old” and “coming into days,” for the reason that the angels have no idea of old age, or of the advancing age which is meant by “coming into days;” but an idea of state in regard to the life in which they are; and therefore when mention is made in the Word of advancement in age, and of old age, the angels who are with man can have no other idea than of the state of life in which the persons are, and in which men are while passing through their ages even to the last; namely, that they thus successively put off what is human and put on what is heavenly. For human life, from infancy to old age, is nothing else than a progression from the world to heaven; and the last age, which is death, is the transition itself. Therefore burial is resurrection, because it is a complete putting off (see n. 2916, 2917). As the angels are in such an idea, nothing else can be signified by “coming into days” and by “old age” in the internal sense which is principally for angels and for men who are angelic minds.

23. Nothing is more common in the Word than for “day” to be used to denote time itself. As in Isaiah:

The day of Jehovah is at hand. Behold, the day of Jehovah cometh. I will shake the heavens, and the earth shall be shaken out of her place, in the day of the wrath of Mine anger. Her time is near to come, and her days shall not be prolonged (Isaiah 13:6, 9, 13, 22).

And in the same Prophet:

Her antiquity is of ancient days. And it shall come to pass in that day that Tyre shall be forgotten seventy years, according to the days of one king (Isaiah 23:7, 15).

As “day” is used to denote time, it is also used to denote the state of that time, as in Jeremiah:

Woe unto us, for the day is gone down, for the shadows of the evening are stretched out (Jeremiah 6:4).

And again:

If ye shall make vain My covenant of the day, and My covenant of the night, so that there be not day and night in their season (Jeremiah 23:20, 25).

And again:

Renew our days, as of old (Lamentations 5:21).
