Luke 4:35, 40-41

Jesus shut him up: “Quiet! Get out of him!” The demonic spirit threw the man down in front of them all and left. The demon didn’t hurt him.

When the sun went down, everyone who had anyone sick with some ailment or other brought them to him. One by one he placed his hands on them and healed them. Demons left in droves, screaming, “Son of God! You’re the Son of God!” But he shut them up, refusing to let them speak because they knew too much, knew him to be the Messiah.
