And I will put enmity
between you [the Serpent] and the woman,
    and between your offspring  and hers [Jesus Christ];
he will crush your head,
and you will strike his heel.” Gen 3:15

But when he saw many of the Pharisees [Jews] and Sadducees coming to where he was baptizing, he said to them: “You brood of vipers! Who warned you to flee from the coming wrath? Matthew 3:7

You brood of vipers, how can you who are evil say anything good? For the mouth speaks what the heart is full of. Matthew 12:34

Woe to you, teachers of the law and Pharisees, you hypocrites! You travel over land and sea to win a single convert, and when you have succeeded, you make them twice as much a child of hell as you are. Matt 23:15

You serpents, you brood of vipers, how are you to escape being sentenced to hell? Matt 23:33 ESV

Jesus to the Jews:

41 You are doing the works your father did.” They said to him, “We were not born of sexual immorality. We have one Father—even God.” 42 Jesus said to them, “If God were your Father, you would love me, for I came from God and I am here. I came not of my own accord, but he sent me. 43 Why do you not understand what I say? It is because you cannot bear to hear my word. 44 You are of your father the devil, and your will is to do your father’s desires. He was a murderer from the beginning, and does not stand in the truth, because there is no truth in him. When he lies, he speaks out of his own character, for he is a liar and the father of lies. 45 But because I tell the truth, you do not believe me. 46 Which one of you convicts me of sin? If I tell the truth, why do you not believe me? 47 Whoever is of God hears the words of God. The reason why you do not hear them is that you are not of God.”48 The Jews answered him, “Are we not right in saying that you are a Samaritan and have a demon?” John 8:41-48

“the Jews, who killed both the Lord Jesus and the prophets, and drove us out, and displease God and oppose all mankind  by hindering us from speaking to the Gentiles that they might be saved—so as always to fill up the measure of their sins. But wrath has come upon them at last!” 1 Thes 2:14-16

10 For there are many who are insubordinate, empty talkers and deceivers, especially those of the circumcision party. 11 They must be silenced, since they are upsetting whole families by teaching for shameful gain what they ought not to teach. 12 One of the Cretans, a prophet of their own, said, “Cretans are always liars, evil beasts, lazy gluttons.”13 This testimony is true. Therefore rebuke them sharply, that they may be sound in the faith, 14 not devoting themselves to Jewish myths and the commands of people who turn away from the truth. Titus 1:10-14

“‘ . . . the slander  of those who say that they are Jews and are not, but are a synagogue of Satan.” Rev 2:9

“Behold, I will make those of the synagogue of Satan who say that they are Jews and are not, but lie—behold, I will make them come and bow down before your feet, and they will learn that I have loved you.” Rev 3:9
