Adam Clarke on Song of Solomon 2:13

The fig tree putteth forth her green figs - The fig tree in Judea bears double crops; the first of which is ripe in spring. But the tree, as I have elsewhere observed, bears figs all the year through, in the climes congenial to it. That is, the fig tree has always ripe or unripe fruit on it. I never saw a healthy tree naked. But in the beginning of spring they grow fast, and become turgid.

The vines with the tender grape - The versions understand this of the flowers of the vine. These were formerly put into the new wine (2 lbs. to every cask) to give it a fine flavour.
