John Gill Commentary Jonah 4:9

"And God said to Jonah, Doest thou well to be angry for the gourd? And he said, I do well to be angry, even unto death." — Jonah 4:9 (ASV)

And God said to Jonah, do you well to be angry for the gourd? &c.] Or, "art you very angry for it?" as the Targum: no mention is made of the blustering wind and scorching sun, because the gourd or plant raised up over him would have protected him from the injuries of both, had it continued; and it was for the loss of that that Jonah was so displeased, and in such a passion. This question is put in order to draw out the following answer, and so give an opportunity of improving this affair to the end for which it was designed: and he said, I do well to be angry, [even] unto death; or, "I am very angry unto death", as the Targum; I am so very angry that I cannot live under it for fretting and vexing; and it is right for me to be so, though I die with the passion of it: how ungovernable are the passions of men, and to what insolence do they rise when under the power of them!
