לְ֭מַכֵּה מְלָכִ֣ים גְּדֹלִ֑ים כִּ֖י לְעוֹלָ֣ם חַסְדּֽוֹ׃
큰 왕들을 치신 이에게 감사하라 그 인자하심이 영원함이로다
Rashi on Psalms
great kings Here he alluded to the thirty-one kings, and he compared for them Pharaoh and his host and the plagues of Egypt to mighty kings, harsher than they. Sihon was equal to all of them, [and Og was equal to all of them (Machzor Vitry)], each one individually, and so did he explain above (135: 11): “Sihon the king of the Amorites and Og the king of Bashan and all the kingdoms of Canaan.” So it is in the Aggadah.
