Jonah 1:11

The sailors asked counsel of Jonah; and hence it appears that they were touched with so much fear as not to dare to do any thing to him. We hence see how much they had improved almost in an instant, since they spared an Israelite, because they acknowledged that among that people the true God was worshipped, the supreme King of heaven and earth: for, without a doubt, it was this fear that restrained them from throwing Jonah immediately into the sea. For since it was certain that through his fault God was displeased with them all, why was it that they did not save themselves by such an expiation? That they then delayed in so great a danger, and dared not to lay hold instantly on Jonah, was an evident proof that they were restrained, as I have said, by the fear of God.

They therefore inquire what was to be done, What shall we do to thee, that the sea may be still to us? (27) for the sea was going, etc. By going Jonah means, that the sea was turbulent: for the sea is said to rest when it is calm, but when it is turbulent, then it is going, and has various movements and tossings. The sea, then, was going and very tempestuous (28) We hence see that God was not satisfied with the disgrace of Jonah, but he purposed to punish his offense still more. It was necessary that Jonah should be led to the punishment which he deserved, though afterwards, he was miraculously delivered from death, as we shall see in its proper place.
