Adam Clarke on Jonah 1:9

I fear the Lord - In this Jonah was faithful. He gave an honest testimony concerning the God he served, which placed him before the eyes of the sailors as infinitely higher than the objects of their adoration; for the God of Jonah was the God of heaven, who made the sea and the dry land, and governed both. He also honestly told them that he was fleeing from the presence of this God, whose honorable call he had refused to obey. See Jon 1:10.
