"Rebekah," it says, "was coming with the daughters of the city to draw water from the well." Rebekah came daily to the wells, daily she drew water. And because she was daily free to be at the wells, therefore she could be found by Abraham's servant and joined in marriage to Isaac. Do you suppose these are fables, and that the Holy Spirit is narrating mere histories in the Scriptures? This is the instruction of souls and spiritual teaching, which trains you and teaches you to come daily to the wells of the Scriptures, to the waters of the Holy Spirit, and always to draw and carry home a full vessel, just as holy Rebekah also did, who could not otherwise have been joined to so great a Patriarch as Isaac, who "was born of promise," except by drawing waters, and by drawing them in such abundance that she could give drink not only to those who were at home, but also to Abraham's servant — and not only to the servant, but that she abounded so far in the waters she drew from the wells that she could also water the camels, "until," it says, "they left off drinking." All the things that are written are mysteries: Christ too wishes to betroth you to himself; for he speaks to you through the prophets, saying: "I will betroth you to myself forever, and I will betroth you to myself in faith and in mercy, and you shall know the Lord." Because, therefore, he wishes to betroth you to himself, he sends this servant ahead to you. This servant is the prophetic word, which, unless you first receive it, you will not be able to be wedded to Christ. Know, however, that no one untrained and unskilled receives the prophetic word, but only one who knows how to draw water from the depth of the well and who knows how to draw it in such abundance that it suffices even for those who seem irrational and perverse, whose figure the camels bear — so that he too may be able to say that "I am a debtor to the wise and to the unwise." Indeed, this servant had thus spoken in his heart: "of these virgins," he says, "who come to the water, whichever shall say to me, 'Drink, and I will water your camels,' she it is who shall be the bride of my lord." So then Rebekah, whose name means patience, when she saw the servant and beheld the prophetic word, "lets down" the "water-jar" from her shoulder. For she lets down the lofty arrogance of Greek eloquence, and, inclining herself to the humble and simple prophetic word, she says: "Drink, and I will water your camels."
