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.
We now then perceive how this passage of Jonah is to be understood, when he says that he fled beyond the sea, at least that he attempted to do so, because he knew that God was gracious; for he would not have deprived God of his service, had not this contrariety disturbed and discouraged his mind, “What! I shall go there as God’s ambassador, in a short time I shall be discovered to be a liar: will not this reproach be cast on the name of God himself? It is therefore better for me to be silent, than that God, the founder of my call, should be ridiculed.” We see that Jonah had a distinct regard to that sort of preaching which we have already referred to. And it hence appears that Jonah gave to the Ninevites more than he thought; for he supposed that he was sent by God, only that the Ninevites might know that they were to be destroyed: but he brought deliverance to them; and this indeed he partly suspected or knew before; for he retained this truth — that God cannot divest himself of his mercy, for he remains ever the same. But when he went forth to execute the duty enjoined on him he certainly had nothing to expect but the entire ruin of the city Nineveh. God in the meantime employed his ministry for a better end and purpose. There is indeed no doubt but that he exhorted the Ninevites to repentance; but his own heart was as it were closed up, so that he could not allow them the mercy of God. We hence see that Jonah was seized with perplexities, so that he could not offer deliverance to the Ninevites, and it was yet offered them by God through his instrumentality.
