Yahweh prepared a great fish to swallow up Jonah, and Jonah was in the belly of the fish three days and three nights.
Before leaving this chapter, it should be noted that Jonah here appeared as a remarkable type of Israel.  Christ of course is the "new Israel," Jonah being also a vivid and instructive type of the Lord Jesus Christ; but it also follows that his life in certain particulars is also typical of the old Israel.
