1 Kings 1:15

Through this attendant of mourning, and (this) hunger, even that sinful state, Nineveh, is freed from the predicted ruin. For repentance for sins had sufficiently commended the fast, keeping it up in a space of three days, starving out even the cattle with which God was not angry. Sodom also, and Gomorrah, would have escaped if they had fasted. This remedy even Ahab acknowledges. When, after his transgression and idolatry, and the slaughter of Naboth, slain by Jezebel on account of his vineyard, Elijah had upbraided him, “How hast thou killed, and possessed the inheritance? In the place where dogs had licked up the blood of Naboth, thine also shall they lick up,”, he “abandoned himself, and put sackcloth upon his flesh, and fasted, and slept in sackcloth. …

He found out every way of knowledge, and showed it to Jacob His son, and Israel His beloved. Afterwards He was seen upon earth, and conversed with men.” And when they read them, they lament and bewail, as themselves suppose, that desolation which happened by Nebuchadnezzar ; but, as the truth shows, they unwillingly make a prelude to that lamentation which will overtake them. …

They despised angels’ food, and sighed for the flesh of Egypt. Moses for forty days and forty nights fasted on Mount Sinai, and showed even then that man does not live on bread alone, but on every word of God. He says to the Lord, “the people is full and maketh idols.” Moses with empty stomach received the law written with the finger of God.
