And Jehovah Elohim prepared a gourd, and made it to come up over Jonah, that it might be a shade over his head, to deliver him from his trouble. And Jonah was exceeding glad because of the gourd.

And it came to pass, when the sun arose, that God prepared a sultry east wind; and the sun beat upon the head of Jonah, so that he fainted; and he requested for himself that he might die, and said, It is better for me to die than to live.
