Deuteronomy 18:15-20
18:15 The LORD your God will raise up for you a prophet like me from among your own people; you shall heed such a prophet.
18:16 This is what you requested of the LORD your God at Horeb on the day of the assembly when you said: "If I hear the voice of the LORD my God any more, or ever again see this great fire, I will die."
18:17 Then the LORD replied to me: "They are right in what they have said.
18:18 I will raise up for them a prophet like you from among their own people; I will put my words in the mouth of the prophet, who shall speak to them everything that I command.
18:19 Anyone who does not heed the words that the prophet shall speak in my name, I myself will hold accountable.
18:20 But any prophet who speaks in the name of other gods, or who presumes to speak in my name a word that I have not commanded the prophet to speak--that prophet shall die."
Mark 1:21-28
1:21 They went to Capernaum; and when the sabbath came, he entered the synagogue and taught.
1:22 They were astounded at his teaching, for he taught them as one having authority, and not as the scribes.
1:23 Just then there was in their synagogue a man with an unclean spirit,
1:24 and he cried out, "What have you to do with us, Jesus of Nazareth? Have you come to destroy us? I know who you are, the Holy One of God."
1:25 But Jesus rebuked him, saying, "Be silent, and come out of him!"
1:26 And the unclean spirit, convulsing him and crying with a loud voice, came out of him.
1:27 They were all amazed, and they kept on asking one another, "What is this? A new teaching--with authority! He commands even the unclean spirits, and they obey him."
1:28 At once his fame began to spread throughout the surrounding region of Galilee.
