Luke 9:42-45 ESV
While he was coming, the demon threw him to the ground and convulsed him. But Jesus rebuked the unclean spirit and healed the boy, and gave him back to his father. And all were astonished at the majesty of God.
But while they were all marveling at everything he was doing, Jesus said to his disciples, “Let these words sink into your ears: The Son of Man is about to be delivered into the hands of men.” But they did not understand this saying, and it was concealed from them, so that they might not perceive it. And they were afraid to ask him about this saying.
