Luke 13:7-9

7And he said unto the vinedresser, Behold, these three years I come seeking fruit on this fig tree, and find none: cut it down; why doth it also cumber the ground?

8And he answering saith unto him, Lord, let it alone this year also, till I shall dig about it, and dung it:

9and if it bear fruit thenceforth, well; but if not, thou shalt cut it down.
