'O God' in the Bible

And he arose and went to Nineveh at the LORD's commandment. Nineveh was a great city unto God, containing three days journey.

But let man and beast be covered with sackcloth, and cry mightily unto God: yea, let them turn every one from his evil way, and from the violence that is in their hands.

Then God saw their actions—that they had turned from their evil ways—so God relented from the disaster He had threatened to do to them. And He did not do it.

So God appointed a worm {at daybreak} the next day, and it attacked the plant, and it withered.

So God said to Jonah, "{Is it right for you to be angry} about the plant?" And he said, "{It is right for me to be angry enough to die}!"
