Forsake their own mercy, &c.— "They who worship idols abandon the mercy of God, render it useless, and reject it, even though offered to them and always ready to save them." Houbigant reads the last clause, Have forsaken their benefactor: and he supposes that Jonah applies this to the mariners who prayed to their gods, before they knew that the true God of heaven and earth, who had raised the storm, was the same who appeased it.
