Jonah 4:10 - Clarke's commentary and critical notes on the Bible

Then said the LORD, Thou hast had pity on the gourd, for the which thou hast not laboured, neither madest it grow; which came up in a night, and perished in a night: Which came up in a night - St. Jerome, speaking of this plant, the kikayon, assigns to it an extraordinary rapidity of growth. It delights in a sandy soil, and in a few days what was a plant grows into a large shrub. But he does not appear to have meant the ricinus; this however is the most likely. The expressions coming up in a night and perishing in a night are only metaphorical to express speedy growth and speedy decay; and so, as we have seen, the Chaldee interprets it, די בליליא הדי הוה ובליליא אוחרנא אבד "which existed this night but in the next night perished;" and this I am satisfied is the true import of the Hebrew phrase.
