Matthew 23:33

But when John saw many of the Pharisees and Sadducees coming to his place of baptism, he said to them, “You brood of vipers, who warned you to flee from the coming wrath?

You brood of vipers, how can you who are evil say anything good? For out of the overflow of the heart, the mouth speaks.

But I tell you that anyone who is angry with his brother will be subject to judgment. Again, anyone who says to his brother, ‘Raca,’ will be subject to the Sanhedrin. But anyone who says, ‘You fool!’ will be subject to the fire of hell.

Then John said to the crowds coming out to be baptized by him, “You brood of vipers, who warned you to flee from the coming wrath?

You belong to your father, the devil, and you want to carry out his desires. He was a murderer from the beginning, refusing to uphold the truth, because there is no truth in him. When he lies, he speaks his native language, because he is a liar and the father of lies.

And I will put enmity between you and the woman, and between your seed and her seed. He will crush your head, and you will strike his heel.”

And the great dragon was hurled down—that ancient serpent called the devil and Satan, the deceiver of the whole world. He was hurled to the earth, and his angels with him.

I am afraid, however, that just as Eve was deceived by the serpent’s cunning, your minds may be led astray from your simple and pure devotion to Christ.

How much more severely do you think one deserves to be punished who has trampled on the Son of God, profaned the blood of the covenant that sanctified him, and insulted the Spirit of grace?

See to it that you do not refuse Him who speaks. For if the people did not escape when they refused Him who warned them on earth, how much less will we escape if we reject Him who warns us from heaven?
