Augustine of Hippo
Catena Aurea · Lukasevangelium 13
He spake also this parable; A certain man had a fig tree planted in his vineyard; and he came and sought fruit thereon, and found none. Then said he unto the dresser of his vineyard, Behold, these three years I come seeking fruit on this fig tree, and find none; cut it down: why cumbereth it the ground? And he answering said unto him, Lord, let it alone this year also, till I shall dig about it, and dung it: And if it bear fruit, well: and if not, then after that thou shalt cut it down.
(ubi sup.) Or, in another sense, the fig tree is the race of mankind. For the first man after he had sinned concealed with fig leaves his nakedness, that is, the members from which we derive our birth.
