In Exodus 4:18, this signifies the continuation of the previous life. (Arcana Coelestia 7014)

In Exodus 13:17, this signifies to fall into falsities. (Arcana Coelestia 8097)

In John 13:3, this signifies to be conceived and to exist from the Divine in Himself, and to be united to Him as soul to body. (Arcana Coelestia 852[9])

2213. 'About this time next year, and Sarah will have a son' means that the Lord would at that point cast off the human rational and put on the Divine Rational. This is clear from the meaning of 'returning at this time of life', or 'at this time next year', as the joining together of the Divine with the Lord's Human, dealt with above in 2193, and from the meaning of 'Sarah's having a son' as the Rational that was to be Divine, also dealt with above, in 2194. 'This time of life', or 'this time next year', denotes the time when Abraham would be entering his hundredth year, which year means when the Lord's Human had become united to the Divine, and the Divine to the Human, as shown above in 1988. There was an interval of a year because 'a year' in the Word does not mean a year but an entire length of time, thus a whole period, whether of a thousand years, or of a hundred, or of ten, or of hours, as also shown already, in 482, 487, 488, 493, 893; and the same applies to a week, dealt with in 2044.
