Rashi on Genesis 10:9/רש"י על בראשית י׳:ט׳

1גבור ציד A MIGHTY HUNTER — He ensnared the minds of people by his words, misleading them to rebel against the Omnipresent (Genesis Rabbah 37:2).

2‘לפני ה BEFORE THE LORD — intending purposely to provoke Him to His face

3על כן יאמר WHEREFORE IT IS SAID — Regarding any man who brazenly acts wickedly — knowing his Master and yet of set purpose rebelling against Him — it is said. “This man is like Nimrod a mighty hunter” (Sifra, Bechukotai, Section 2 1-2).
