Kommentar zu Tehillim 45:6

Your arrows are sharpened, etc., in the heart of the king’s enemies Heb. שְּׁנוּנִים, is aiguises in French, sharpened. This is a transposed verse. We find that the disciples are called arrows, as it is stated (above 127:4): “As arrows in the hand of a mighty man, so are the children of youth.” And Torah scholars who argue with each other about halachah are called enemies to each other for the time, as it is stated: “they will not be ashamed when they speak with the enemies in the gate.”

nations shall fall under you As a reward for Torah, nations shall fall under Israel.
