וַֽ֭יַּהֲרֹג מְלָכִ֣ים אַדִּירִ֑ים כִּ֖י לְעוֹלָ֣ם חַסְדּֽוֹ׃
И убил могучих царей, ибо вовек милость Его.
Midrash BeChiddush
וַֽ֭יַּהֲרֹג מְלָכִ֣ים אַדִּירִ֑ים “God slew mighty kings.” (Ps. 136: 18) refers to the generation of Nachor. In his days Nimrod ruled who caused the whole world to rebel against God. He brought anger upon the world, and therefore he was called Nachor, the same letters of Haron.
