Jonah 1:16 - Joseph Benson’s Commentary on the Old and New Testaments

Then the men feared the Lord exceedingly They were convinced of the power and greatness of that God whom Jonah worshipped: which appeared both in raising this storm, and in so suddenly laying it. And offered sacrifice unto the Lord Or JEHOVAH; and made vows As it is not probable that they offered a sacrifice on shipboard, this seems to be spoken of what they did when they came safe to the port for which they were bound; namely that they made a public acknowledgment, by sacrifice and other religious acts, of the mercy they had received of God, and of his wonderful power, the effects of which they had witnessed.
