Then Jonah prayed to the Lord his God from inside the fish. He said, “I cried out to the Lord in my great trouble, and he answered me. I called to you from the land of the dead, and Lord, you heard me!”
Jonah 2:1-2
For just as Jonah was three days and three nights in the belly of the great fish, so will the Son of Man be three days and three nights in the heart of the earth.
Matthew 12:40
