20 Then he went home, and the crowd gathered again, so that they could not even eat. 21 And when his family heard it, they went out to seize him, for they were saying, “He is out of his mind.” 22 And the scribes who came down from Jerusalem were saying, “He is possessed by Beelzebul,” and “by the prince of demons he casts out the demons.”
Mark 6:1-3 (ESV)
1 He went away from there and came to his hometown, and his disciples followed him. 2 And on the Sabbath he began to teach in the synagogue, and many who heard him were astonished, saying, “Where did this man get these things? What is the wisdom given to him? How are such mighty works done by his hands? 3 Is not this the carpenter, the son of Mary and brother of James and Joses and Judas and Simon? And are not his sisters here with us?” And they took offense at him.
Mark 8:27-30 (ESV)
27 And Jesus went on with his disciples to the villages of Caesarea Philippi. And on the way he asked his disciples, “Who do people say that I am?” 28 And they told him, “John the Baptist; and others say, Elijah; and others, one of the prophets.” 29 And he asked them, “But who do you say that I am?” Peter answered him, “You are the Christ.” 30 And he strictly charged them to tell no one about him.
