And then shall he send forth the angels. This represents the great harvest at the end of the world, when the angel-reapers shall be sent forth to separate the wicked from the just. The elect will be gathered from the four winds ( ἐκ τῶν πεσσάρων ἀνέμων); literally, out of the four winds—the winds representing figuratively every corner of the world; or, from the uttermost part of the earth to the uttermost part of heaven. At its extremities, in the horizon, there appears to be the end alike of earth and of heaven, as though earth and heaven joined, and the heaven terminated by melting into the earth and becoming one with it. The expression simply means, "from horizon to horizon," or from every part of the earth.
Now from the fig tree learn her parable; that is, her own particular teaching. Our Lord makes frequent mention and use of the fig tree, as we have seen already. It is probable that a fig tree may have been near to them. When her branch is now become tender, and putteth forth its leaves, ye know that the summer is nigh. The branch ( κλάδος) would be the young shoot, now become tender under the quickening influences of the spring; and this was an evident sign that the summer was at hand. The Asiatic fig tree requires a considerable amount of warmth to enable it to put forth leaves and fruit. Its rich flavour requires a summer heat to mature it. Aristotle says that the fig is the choice food of bees, from which they make their richest honey. Then the fig tree does not flower after the ordinary manner; but produces flower and fruit at once from the tree, and rapidly matures the fruit. The lesson, therefore, from the fig tree is this—the speed with which she ripens her fruit when she feels the warmth of summer. In like manner, as soon as the disciples perceived the signs of Christ's coming, they were to learn that he was close at hand, as certainly as the ripening fruit of the fig tree showed that summer was at hand.
