וַיֹּ֨אמֶר יְהוָ֜ה אֶל־יֵה֗וּא יַ֤עַן אֲשֶׁר־הֱטִיבֹ֙תָ֙ לַעֲשׂ֤וֹת הַיָּשָׁר֙ בְּעֵינַ֔י כְּכֹל֙ אֲשֶׁ֣ר בִּלְבָבִ֔י עָשִׂ֖יתָ לְבֵ֣ית אַחְאָ֑ב בְּנֵ֣י רְבִעִ֔ים יֵשְׁב֥וּ לְךָ֖ עַל־כִּסֵּ֥א יִשְׂרָאֵֽל׃
永恆者對耶戶說：「因為你做得好，行了我眼中看為正的事，照著我心中所想的一切對待了亞哈家，所以你的子孫必坐在以色列的王位上，直到第四代。」
Rashi
Four generations of your sons. Four generations12The four generations of Yeihu’s descendants are: Yehoachaz, Yehoash, Yorovom and Zecharyoh. [as reward] for your having destroyed the house of Achov, which reigned for four generations: Omri, Achov, Achazyoh, and Yehorom.
