Иона 1:15

After they had prayed thus, they cast Jonah into the sea, and "the sea stood still (ceased) from its raging." The sudden cessation of the storm showed that the bad weather had come entirely on Jonah's account, and that the sailors had not shed innocent blood by casting him into the sea. In this sudden change in the weather, the arm of the holy God was so suddenly manifested, that the sailors "feared Jehovah with great fear, and offered sacrifice to Jehovah" - not after they landed, but immediately, on board the ship - "and vowed vows," i.e., vowed that they would offer Him still further sacrifices on their safe arrival at their destination.

In this chapter we have, I. A command given to Jonah to preach at Nineveh (Jon 1:1, Jon 1:2). II. Jonah's disobedience to that command (Jon 1:3). III. The pursuit and arrest of him for that disobedience by a storm, in which he was asleep (Jon 1:4-6). IV. The discovery of him, and his disobedience, to be the cause of the storm (Jon 1:7-10). V. The casting of him into the sea, for the stilling of the storm (Jon 1:11-16). VI. The miraculous preservation of his life there in the belly of a fish (Jon 1:17), which was his reservation for further services.
