Genesis 13:3

And he returned by the way he had come from Bethel in the south. For by the south, we indeed tend towards Bethel through the light of heavenly knowledge, and through the inspiration of intimate love, we hasten by frequent steps of good works to the entrance of the house of God, which Bethel signifies; namely, that house which, as the Apostle says, is not made with hands, but is eternal in the heavens (II Cor. V, 1), which the Prophet desired to see, when he said: Lord, I have loved the beauty of your house, and the place of the tabernacle of your glory (Psalm XXVI, 8).

Consider, I ask you, how he was a lover of peace and quiet and was constantly attentive to divine worship. The text says, remember, that he went down to that place where he had previously built the altar. By calling on the name of God he right from the very beginning fulfilled in anticipation that saying of David, "I would rather be of no account in the house of my God than take up residence in sinners' dwellings." In other words, solitude turned out to be preferred by him for invoking the name of God, instead of the cities. After all, he well knew that cities' greatness is not constituted by multitude of inhabitants but by the virtue of its residents. Hence too the desert proved to be more desirable than the cities, adorned as it was by the just man's virtue and thus a more resplendent vision than the whole world.

To the place where he had previously pitched his tent between Bethel and Ai: at the place of the altar which he had made formerly, and he called upon the name of the Lord. It is noteworthy that blessed Abraham, progressing in his chosen journey, is said to have returned from Bethel either from the south or through the south, yet it is not added that he entered the same city; but he is said to have reached the area between this place and Ai, and there he invoked the Lord. This place of prayer is mentioned to be situated on a mountain, because obviously, the elect, still restrained by the bond of flesh and set in the progress of virtues, strive with the whole intention of their mind to reach the house of heavenly habitation, hasten to it with continuous steps of good works; but they cannot yet enter it, nor can they see its King and citizens in their beauty: however, between the acceptance of faith by which they are consecrated to the Lord, and the entrance to the kingdom in which they desire to see Him, they climb the height of good action as a peak of a lofty mountain. For Ai indeed, or Aggai, as the ancient translators rendered the name of that city, is interpreted as Question or Festival: which name, evidently, most fittingly suits the time when each of the faithful is consecrated to the Lord with the saving sacraments: about which the Apostle admonishes saying: Do not grieve the Holy Spirit of God, by whom you were sealed for the day of redemption (Eph. 4:30). For what great festivity of mind it is to be redeemed from the power of darkness, and by the illumination of the Holy Spirit to be made a seal of the true King? Which city of invincible faith can also rightly be called Question: for by this the elect have learned either to seek the Lord from whom they have strayed farther away, or the Lord Himself, as a good shepherd, has shown Himself to have sought them as His sheep, according to what He says: The Son of man came to seek and to save the lost (Luke 19:10). Moreover, the saints build on the aforementioned mountain of good conversation an altar to the Lord, nothing else surely than their body and soul, in which they also invoke His name, knowing that without the help of His name they could neither begin the path of righteousness, nor complete the course of a good intention. We have thus carefully explicated these things about the place of Abraham's…
