הוּא הֵשִׁיב אֶת גְּבוּל יִשְׂרָאֵל מִלְּבוֹא חֲמָת עַד יָם הָעֲרָבָה כִּדְבַר ה' אֱלֹקי יִשְׂרָאֵל אֲשֶׁר דִּבֶּר בְּיַד עַבְדּוֹ יוֹנָה בֶן אֲמִתַּי הַנָּבִיא אֲשֶׁר מִגַּת הַחֵפֶר
He restored the border of Israel from the entrance to Hamas to the sea of Arava according to the word of Hashem, the G-d of Israel, that He spoke through the hand of His servant Jonah, the son of Amittai, the prophet, who was from Gas-Hachefer.
Did you know that Yonah (Jonah) was in the Book of Kings? Well, here he is! But whatever prophecy is alluded to here is unrecorded – and problematic, since we have a tradition that G-d only spoke with Yonah twice and this would make a third time! The Radak cites a discussion on this matter from Talmud Yevamos 98a. One explanation is that G-d only spoke with Yonah twice about Nineveh but this is a different matter. The other explanation is that Yonah did not have a prophecy here; what it means is that the Jews repented and turned themselves around at this time just like the people of Nineveh did in response to Yonah’s prophecy.
