Thus, Jonah, despite his attempt to run away, converted these sailors to the worship of Yahweh. Once the sea was calm, they were even more fearful of Jonah’s God, Yahweh. Thus, they offered a sacrifice and made vows to Yahweh, the God who calmed the seas.
Jonah was quite frank with these sailors. He told them to pick him up and throw him into the sea. Then the sea would quiet down for them. He knew that this great storm came to them because of him, since Yahweh was mad at him.
These sailors said to each other that they wanted to cast lots, a common way of making decisions. They wanted to know who was the cause of this great storm. Jonah won the lottery, as the lot fell to him. In other words, they considered that Jonah was the cause of the storm.
