“From the fig tree,
Learn its lesson!
As soon as its branch
Becomes tender,
It puts forth its leaves.
Then you know
That summer
Is near.”
Ἀπὸ δὲ τῆς συκῆς μάθετε τὴν παραβολήν· ὅταν ἤδη ὁ κλάδος αὐτῆς γένηται ἁπαλὸς καὶ τὰ φύλλα ἐκφύῃ, γινώσκετε ὅτι ἐγγὺς τὸ θέρος
This is exactly the same, word for word, in Mark, chapter 13:28, but in Luke, chapter 21:29-30, almost word for word. Earlier in chapter 21:19-20, Jesus had cursed a fig tree for not having fruit, but here there was a lesson or a little parable to be learned (μάθετε τὴν παραβολήν) from the fig tree (Ἀπὸ δὲ τῆς συκῆς). As soon as its branches or shoots became tender (ὅταν ἤδη ὁ κλάδος αὐτῆς γένηται ἁπαλὸς), it would put forth its leaves (καὶ τὰ φύλλα ἐκφύῃ). Then you would know that summer was near (γινώσκετε ὅτι ἐγγὺς τὸ θέρος). In other words, the early leaves on a tree indicated that summer was coming. Let’s hope that summer keeps coming.
