New Testament

Matthew 9:27-34

27 As Jesus went on from there, two blind men began to follow him, shouting, “Have mercy on us, Son of David!” 28 When he went into the house, the blind men came to him. Jesus said to them, “Do you believe that I am able to do this?” They said to him, “Yes, Lord.” 29 Then he touched their eyes saying, “Let it be done for you according to your faith.” 30 And their eyes were opened. Then Jesus sternly warned them, “See that no one knows about this!” 31 But they went out and spread the news about him throughout that entire region.

32 As they were going away, a man who was demon-possessed and unable to speak was brought to him. 33 After the demon was cast out, the man who had been mute began to speak. The crowds were amazed and said, “Never has anything like this been seen in Israel!” 34 But the Pharisees said, “By the prince of demons he casts out demons!”

Testament of Solomon 6:1-3

And I summoned again to stand before me Beelzeboul, the prince of demons, and I sat him down on a raised seat of honour, and said to him: "Why art thou alone, prince of the demons?" And he said to me: "Because I alone am left of the angels of heaven that came down. For I was first angel in the first heaven being entitled Beelzeboul. And now I control all those who are bound in Tartarus. But I too have a child, and he haunts the Red Sea. And on any suitable occasion he comes up to me again, being subject to me; and reveals to me what he has done, and I support him.
