וַֽ֭יַּהֲרֹג מְלָכִ֣ים אַדִּירִ֑ים כִּ֖י לְעוֹלָ֣ם חַסְדּֽוֹ׃
유명한 왕들을 죽이신 이에게 감사하라 그 인자하심이 영원함이로다
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.
