'Enough' in the Bible

Then God said to Jonah, “Do you have a good reason to be angry about [the loss of] the plant?” And he said, “I have a [very] good reason to be angry, angry enough to die!”

Should I not have compassion on Nineveh, the great city in which there are more than 120,000 [innocent] persons, who do not know the difference between their right and left hand [and are not yet accountable for sin], as well as many [blameless] animals?”
