John Calvin Commentary Joel 1:12

"The vine is withered, and the fig-tree languisheth; the pomegranate-tree, the palm-tree also, and the apple-tree, even all the trees of the field are withered: for joy is withered away from the sons of men." — Joel 1:12 (ASV)

The Prophet now concludes his subject, which was that as God executed judgments so severe on the people, it was a wonder that they remained stupefied when they were thus reduced to extreme hardship. The vine, he says, has dried up, and every kind of fruit; he adds the fig-tree, afterwards the רמון remun, the pomegranate (for so they render it), the palm, the apple-tree, and all trees.

And this sterility was a clear sign of God’s wrath; and it would have been so regarded if people had not either wholly deceived themselves or become hardened against all punishments. Now this αναὶσθησὶα (insensibility) is, so to speak, the very summit of evils; that is, when people do not feel their own calamities, or at least do not understand that they are inflicted by the hand of God.
