That evening at sundown they brought to him all who were sick or oppressed by demons. And the whole city was gathered together at the door. And he healed many who were sick with various diseases, and cast out many demons. And he would not permit the demons to speak, because they knew him.
(Mark 1:32-34 ESV)
Jesus continues healing people and casting out the demons showing his authority as the Son of God. It’s probably a bit weird that Jesus would not permit the demons to speak of Jesus’ true nature, but it’s so that Jesus can control the way in which people will come to know who he really is.
