'Offspring' in the Bible

But when he saw many of the Pharisees and Sadducees coming to his baptism, he said unto them, Ye offspring of vipers, who warned you to flee from the wrath to come?

Ye offspring of vipers, how can ye, being evil, speak good things? for out of the abundance of the heart the mouth speaketh.

Ye serpents, ye offspring of vipers, how shall ye escape the judgment of hell?
