Jonah 1:12

Take me up, and cast me into the sea -Neither might Jonah have said this, nor might the sailors have obeyed it, without the command of God. Jonah might will alone to perish, who had alone offended; but, without the command of God, the Giver of life, neither Jonah nor the sailors might dispose of the life of Jonah. But God willed that Jonah should be cast into the sea - where he had gone for refuge - that (Wisdom 11:16) wherewithal he had “sinned, by the same also he might be punished” as a man; and, as a prophet, that he might, in his three days’ burial, prefigure Him who, after His Resurrection, should convert, not Nineveh, but the world, the cry of whose wickedness went up to God.
