Luke 13:6-9 - The Parable Of The Barren Fig Tree
6 Then he gave them this parable. "A man had a fig tree planted in his vineyard, and he came to look for fruit on it, but found none. 7 So he said to the gardener. "'See, for years I have come looking for fruit on this tree, and found none. Cut it down. Why should it actually cumber the ground?'
8 "But the gardener answered him. 'Lord, let it alone this year also, till I have dug around it, and fertilized it. 9 "If after that it bears fruit, well and good; but if not you shall cut it down.'"
