"He did not call them Abraham's children, but a "brood of vipers" [Matt. 3:7]. Oh, that was too insulting for the noble blood and race of Israel, and they declared, "He has a demon' [Matt 11:18]. Our Lord also calls them a "brood of vipers"; furthermore in John 8 [:39,44] he states: "If you were Abraham's children ye would do what Abraham did... You are of your father the devil. It was intolerable to them to hear that they were not Abraham's but the devil's children, nor can they bear to hear this today."
