Matthew 24:32-35

Now from the fig tree learn her parable: when her branch is now become tender, and putteth forth its leaves, ye know that the summer is nigh; even so ye also, when ye see all these things, know ye that he is nigh, even at the doors. Verily I say unto you, This generation shall not pass away, till all these things be accomplished. Heaven and earth shall pass away, but my words shall not pass away.
