Arcana Coelestia # 3185
3185. 'And they blessed Rebekah and said to her' means heartfelt desires resulting from Divine enlightenment. This is clear from the meaning of 'blessing', when bidding farewell to someone who is leaving, as expressing heartfelt desires for their happiness. The fact that here those desires are the result of Divine enlightenment is evident from what follows immediately after and also for the reason that enlightenment flows into the natural man by way of the affection for truth, which is 'Rebekah', when being introduced into good, which is 'Isaac'.
Genesis 22:15-17
15
The angel of Yahweh called to Abraham a second time out of the sky,
16
and said, "I have sworn by myself, says Yahweh, because you have done this thing, and have not withheld your son, your only son,
17
that I will bless you greatly, and I will multiply your seed greatly like the stars of the heavens, and like the sand which is on the seashore. Your seed will possess the gate of his enemies.
