He prayed to Yahweh, and said, "Please, Yahweh, wasn't this what I said when I was still in my own country? Therefore I hurried to flee to Tarshish, for I knew that you are a gracious God, and merciful, slow to anger, and abundant in loving kindness, and you repent of the evil.
For he immediately adds,For I know that thou art a God full of grace, and merciful, slow to wrath, etc. It is a wonder that Jonah withdrew from his lawful call; for he knew that God was merciful, and there is no stronger stimulant than this to stir us on, when God is pleased to use our labor: and we know that no one can with alacrity render service to God except he be allured by his paternal kindness. Hence no one will be a willing Prophet or Teacher, except he is persuaded that God is merciful. Jonah then seems here to reason very absurdly when he says, that he withdrew himself from his office, because he knew that God was merciful. But how did he know this? By the law of God; for the passage is taken from Exodus 33:1, where is described that remarkable and memorable vision, in which God offered to Moses a view of himself: and there was then exhibited to the holy Prophet, as it were, a living representation of God, and there is no passage in the law which expresses God’s nature more to the life; for God was then pleased to make himself known in a familiar way to his servant.
