Luke 21:29-33

And he spake to them a parable: Behold the fig tree, and all the trees: when they now shoot forth, ye see it and know of your own selves that the summer is now nigh. Even so ye also, when ye see these things coming to pass, know ye that the kingdom of God is nigh. Verily I say unto you, This generation shall not pass away, till all things be accomplished. Heaven and earth shall pass away: but my words shall not pass away.
