John Gill Commentary Proverbs 30:14

"There is a generation whose teeth are [as] swords, and their jaw teeth [as] knives, To devour the poor from off the earth, and the needy from among men." — Proverbs 30:14 (ASV)

[There is] a generation whose teeth [are as] swords As sharp as swords; like such the beasts of prey have; cruel, barbarous, and inhuman creatures; see (Psalms 57:4).

and their jaw teeth as knives exceeding sharp and biting: to devour the poor from off the earth, and the needy from [among] men : by their tyranny, oppression, and cruelty, to deprive them of the little they have; and even to take away their lives from them, and utterly destroy them.

Of this disposition are all tyrants and persecutors: such were Rome Pagan, compared to a red dragon in the times of the ten Heathen persecutions; and such is Rome Papal, signified by a beast, like a leopard, bear, and lion; and which has been drunk with the blood of the saints.
