Jonah is angry because the Lord showed mercy
1Jonah was really upset and angry. 2#Exod 34.6So he prayed:
Our Lord, I knew from the very beginning that you wouldn't destroy Nineveh. That's why I left my own country and headed for Spain. You are a kind and merciful God, and you are very patient. You always show love, and you don't like to punish anyone, not even foreigners.
3 # 1 King 19.4 Now let me die! I'd be better off dead.
4The Lord replied, “What right do you have to be angry?”
5Jonah then left through the east gate of the city and made a shelter to protect himself from the sun. He sat under the shelter, waiting to see what would happen to Nineveh.
6The Lord made a vine grow up to shade Jonah's head and protect him from the sun. Jonah was very happy to have the vine, 7but early the next morning the Lord sent a worm to chew on the vine, and the vine dried up. 8During the day the Lord sent a scorching wind, and the sun beat down on Jonah's head, making him feel faint. Jonah was ready to die, and he shouted, “I wish I were dead!”
9But the Lord asked, “Jonah, do you have the right to be angry about the vine?”
“Yes, I do,” he answered, “and I'm angry enough to die.”
10But the Lord said:
You are concerned about a vine that you did not plant or take care of, a vine that grew up in one night and died the next. 11In that city of Nineveh there are more than a hundred and twenty thousand people who cannot tell right from wrong, and many cattle are also there. Don't you think I should be concerned about that big city?
