Kabbalah к Берешит 24:67

It may be objected that in the light of the previous argument, a man is in a state of more honor on a journey than at home, by virtue of the heavenly mate who is then with him. This is not so. At home, the wife is the foundation of a man’s house, inasmuch as it is by virtue of her that the Presence does not leave the house. So the verse, “and Isaac brought her into his mother Sarah’s tent” {Gen. 24:67}, our masters have interpreted to mean that the Divine Presence came to Isaac’s house along with Rebecca.
