During the course of the wedding the wine ran out. The wine is interior devotion, about which Psalm 103:15 says: "Wine cheers the human heart." And Matthew 9:17 reads: "No one places new wine in old wineskins." This wine runs out when men and women become arid and lacking in devotion, as the holy soul says in Psalm 142:6: "My soul is like earth without water in your regard."-- But at the petition of the Virgin who commiserates with those in misery, God filled the water jars with the water of compunction, which is changed into the sweetness of devotion. Thus it is said in Exodus 15:25 that the waters of Meribah "were changed into sweet water."
