1Then the word of the LORD came to Jonah the second time, saying, 2"Arise, go to Nin'eveh, that great city, and proclaim to it the message that I tell you." 3So Jonah arose and went to Nin'eveh, according to the word of the LORD. Now Nin'eveh was an exceedingly great city, three days' journey in breadth. 4Jonah began to go into the city, going a day's journey. And he cried, "Yet forty days, and Nin'eveh shall be overthrown!" 5And the people of Nin'eveh believed God; they proclaimed a fast, and put on sackcloth, from the greatest of them to the least of them. 6Then tidings reached the king of Nin'eveh, and he arose from his throne, removed his robe, and covered himself with sackcloth, and sat in ashes. 7And he made proclamation and published through Nin'eveh, "By the decree of the king and his nobles: Let neither man nor beast, herd nor flock, taste anything; let them not feed, or drink water, 8but let man and beast be covered with sackcloth, and let them cry mightily to God; yea, let every one turn from his evil way and from the violence which is in his hands. 9Who knows, God may yet repent and turn from his fierce anger, so that we perish not?" 10When God saw what they did, how they turned from their evil way, God repented of the evil which he had said he would do to them; and he did not do it.
Psalms 51:3-4, 12-13, 18-19
1Have mercy on me, O God, according to thy steadfast love; according to thy abundant mercy blot out my transgressions. 2Wash me thoroughly from my iniquity, and cleanse me from my sin! 10Create in me a clean heart, O God, and put a new and right spirit within me. 11Cast me not away from thy presence, and take not thy holy Spirit from me. 16For thou hast no delight in sacrifice; were I to give a burnt offering, thou wouldst not be pleased. 17The sacrifice acceptable to God is a broken spirit; a broken and contrite heart, O God, thou wilt not despise.
29When the crowds were increasing, he began to say, "This generation is an evil generation; it seeks a sign, but no sign shall be given to it except the sign of Jonah. 30For as Jonah became a sign to the men of Nin'eveh, so will the Son of man be to this generation. 31The queen of the South will arise at the judgment with the men of this generation and condemn them; for she came from the ends of the earth to hear the wisdom of Solomon, and behold, something greater than Solomon is here. 32The men of Nin'eveh will arise at the judgment with this generation and condemn it; for they repented at the preaching of Jonah, and behold, something greater than Jonah is here.
