Matthew Poole and continuators on Genesis 10:9

9. He was a mighty Hunter before the LORD : Wherefore it is said , Even as Nimrod the mighty Hunter before the LORD.

First of Beasts, and by that occasion of men. For when men were few and lived dispersedly, and wild Beasts abounded, and most of all in those parts, by Hunting and Destroying of those Beasts, he got much reputation and favour with men, who thereby were secured in their dwellings. In confidence hereof, and having this occasion to gather great Companies of the youngest and strongest men together to himself, by their help he established a Tyranny and Absolute Power over Men, ensnaring, hunting after, and destroying like Beasts, all those men who opposed his dominion. Tyrants and Persecutors are oft in Scripture called Fowlers and Hunters, as Psal. 91. 3. Ier. 16. 16. Lament. 3. 52. and 4. 18.

An aggravation of his crime, that it was done in Gods presence, impudently and in contempt both of God, who had so lately manifested his derestation of this sin by the destruction of the World, amongst other Sins, for this very sin of violence, Gen. 6. 13. and of his great Grand-Father Noah then living and Preaching, who probably did admonish him of the wickedness and danger of this practise. Thus he shewed that he neither feared God nor reverenced Man, if they withstood him in his usurpation of Dominion.

It became a Proverb, when any man was haughty and cruel and tyrannical and that joyned with impudence and obstinacy, That he was another Nimrod.
