Remember at the time of the sin of Adam and Eve they clothed themselves- with what? Fig leaves. That was their first act after the fall.
So now Jesus is making the same figure of the fig tree the very last of His wondrous signs. Just as He was headed toward the cross, He cursed a fig tree – not every fig tree, but that one alone for its symbolic significance – saying: “May no one ever eat fruit of you again.”
In this way the curse laid upon Adam and Eve was bring reversed. For they had clothed themselves with fig leaves.
Cyril of Jerusalem (313-386)
