Charles Ellicott Commentary Luke 21:29

"And he spake to them a parable: Behold the fig tree, and all the trees:" — Luke 21:29 (ASV)

And all the trees.—The addition is peculiar to St. Luke. It confirms the impression that the words, which were spoken just before the Passover, when the flush of springtime life was seen in every grove and forest, were suggested by what met the eye of the disciples on the Mount of Olives. (See Note on Matthew 24:32.) One such tree, we know, had been found in full foliage (Matthew 21:19).
