Yahweh prepared a great fish to swallow up Jonah, and Jonah was in the belly of the fish three days and three nights.
Here God controlled the traditionally uncontrollable to spare Jonah’s life. The God who is great enough to control it could control anything, and He used His power for a loving purpose. This is more remarkable since Jonah, as God’s servant, had rebelled against his Master. God’s method of deliverance therefore reveals both His great power and His gracious heart.
