The whole chapter is here, a verse to a line.
וַיְהִי דְבַר־יְהוָה אֶל־יוֹנָה שֵׁנִית לֵאמֹֽר׃
And the word of the LORD came unto Jonah the second time, saying:
קוּם לֵךְ אֶל־נִינְוֵה הָעִיר הַגְּדוֹלָה וִּקְרָא אֵלֶיהָ אֶת־הַקְּרִיאָה אֲשֶׁר אָנֹכִי דֹּבֵר אֵלֶֽיךָ׃
’Arise, go unto Nineveh, that great city, and make unto it the proclamation that I bid thee.’
וַיָּקָם יוֹנָה וַיֵּלֶךְ אֶל־נִינְוֵה כִּדְבַר יְהוָה וְנִינְוֵה הָיְתָה עִיר־גְּדוֹלָה לֵאלֹהִים מַהֲלַךְ שְׁלֹשֶׁת יָמִֽים׃
So Jonah arose, and went unto Nineveh, according to the word of the LORD. Now Nineveh was an exceeding great city, of three days’journey.
וַיָּחֶל יוֹנָה לָבוֹא בָעִיר מַהֲלַךְ יוֹם אֶחָד וַיִּקְרָא וַיֹּאמַר עוֹד אַרְבָּעִים יוֹם וְנִינְוֵה נֶהְפָּֽכֶת׃
And Jonah began to enter into the city a day’s journey, and he proclaimed, and said: ‘Yet forty days, and Nineveh shall be overthrown.’
וַיַּאֲמִינוּ אַנְשֵׁי נִינְוֵה בֵּאלֹהִים וַיִּקְרְאוּ־צוֹם וַיִּלְבְּשׁוּ שַׂקִּים מִגְּדוֹלָם וְעַד־קְטַנָּֽם׃
And the people of Nineveh believed God; and they proclaimed a fast, and put on sackcloth, from the greatest of them even to the least of them.
וַיִּגַּע הַדָּבָר אֶל־מֶלֶך נִינְוֵה וַיָּקָם מִכִּסְאוֹ וַיַּעֲבֵר אַדַּרְתּוֹ מֵעָלָיו וַיְכַס שַׂק וַיֵּשֶׁב עַל־הָאֵֽפֶר׃
And the tidings reached the king of Nineveh, and he arose from his throne, and laid his robe from him, and covered him with sackcloth, and sat in ashes.
וַיַּזְעֵק וַיֹּאמֶר בְּנִינְוֵה מִטַּעַם הַמֶּלֶךְ וּגְדֹלָיו לֵאמֹר הָאָדָם וְהַבְּהֵמָה הַבָּקָר וְהַצֹּאן אַל־יִטְעֲמוּ מְאוּמָה אַל־יִרְעוּ וּמַיִם אַל־יִשְׁתּֽוּ׃
And he caused it to be proclaimed and published through Nineveh by the decree of the king and his nobles, saying: ‘Let neither man nor beast, herd nor flock, taste any thing; let them not feed, nor drink water;
וְיִתְכַּסּוּ שַׂקִּים הָאָדָם וְהַבְּהֵמָה וְיִקְרְאוּ אֶל־אֱלֹהִים בְּחָזְקָה וְיָשֻׁבוּ אִישׁ מִדַּרְכּוֹ הָרָעָה וּמִן־הֶחָמָס אֲשֶׁר בְּכַפֵּיהֶֽם׃
but let them be covered with sackcloth, both man and beast, and let them cry mightily unto God; yea, let them turn every one from his evil way, and from the violence that is in their hands.
מִי־יוֹדֵעַ יָשׁוּב וְנִחַם הָאֱלֹהִים וְשָׁב מֵחֲרוֹן אַפּוֹ וְלֹא נֹאבֵֽד׃
Who knoweth whether God will not turn and repent, and turn away from His fierce anger, that we perish not?’
וַיַּרְא הָאֱלֹהִים אֶת־מַעֲשֵׂיהֶם כִּי־שָׁבוּ מִדַּרְכָּם הָרָעָה וַיִּנָּחֶם הָאֱלֹהִים עַל־הָרָעָה אֲשֶׁר־דִּבֶּר לַעֲשׂוֹת־לָהֶם וְלֹא עָשָֽׂה׃
And God saw their works, that they turned from their evil way; and God repented of the evil, which He said He would do unto them; and He did it not.
