To add to Ephesians 2:8's comment above, one writer has Jesus cursing the fig tree as he approached the temple while the other has him cursing it as he is leaving the temple. The idea is that the fig tree was cursed at the temple. Jesus went to the temple seeking the "fruits" of righteousness. He found none there. The fig tree is in fact Israel, but specifically Jerusalem, and more specifically the temple. Finding no fruit at the temple he cursed it to "never bear fruit again". Shortly after the temple was permanently destroyed and hasn't produced fruit since. If we look at the condition of Jerusalem over the years since it is not hard to imagine why the writer of the Revelation described it as he did: Rev 18:2 And he cried mightily with a strong voice, saying, Babylon the great is fallen, is fallen, and is become the habitation of devils, and the hold of every foul spirit, and a cage of every unclean and hateful bird. Notice that the writer says "is fallen, is fallen", i.e., fallen twice. It was the second time the temple had been destroyed.
