Jonah 4:2

And he prayed unto the Lord - Jonah, at least, did not murmur or complain of God. He complained to God of Himself. He expostulates with Him. Shortsighted indeed and too wedded to his own will! Yet his will was the well-being of the people whose prophet God had made him. He tells God, that this it was, which he had all along dreaded. He softens it, as well as he can, by his word, “I pray Thee,” which expresses deprecation anti-submissiveness. Still he does not hesitate to tell God that this was the cause of his first rebellion! Perilous to the soul, to speak without penitence of former sin; yet it is to God that he speaks and so God, in His wonderful condescension, makes him teach himself.

I knew that Thou art a gracious God - He repeats to God to the letter His own words by Joel Joel 2:13. God had so revealed Himself anew to Judah. He had, doubtless, on some repentance which Judah had shown, turned away the evil from them. And now by sending him as a preacher of repentance, He implied that He would do the same to the enemies of his country. God confirms this by the whole sequel. Thenceforth then Israel knew, that to the pagan also God was intensely, infinitely full of gracious and yearning love nay (as the form rather implies. ) mastered (so to speak) by the might and intensity of His gracious love, “slow to anger” and delaying it, “great in loving tenderness,” and abounding in it; and that toward them also, when the evil is about to be inflicted, or has been partially or wholly inflicted, He will repent of it and replace it with good, on the first turning of the soul or the nation to God.
