Marriage #34
34. (19) Conjugial love depends upon the wife's love, and such too is the husband's love reciprocally; the wife's love does not depend on her husband's love. The reason is that just as the will acts on the understanding, good acts on truth; that is why it is said that a man ought to cleave to his wife. The reverse is true of those who are not in conjugial love.
Arcana Coelestia #2193
2193. That 'I will certainly return to you about this time next year' means the joining together of the Divine with the Human is clear from the fact that Jehovah's coming to Abraham represented the Divine Perception which the Lord prepared Himself to receive, and so represented a joining together, as shown above. Thus the promise that He would certainly return to him has a similar meaning, namely the joining together of the Divine with the Human. 'At this time of life' is at the same time in the following year.
