John Mark
Mark 9:22ESV·traditional attribution

And it has often cast him into fire and into water, to destroy him. But if you can do anything, have compassion on us and help us.”

John Calvin Reformed @genevareformer

22. If thou canst do any thing, have compassion on us, and help us. We see how little honor he renders to Christ; for, supposing him to be some prophet, whose power was limited, he approaches to him with hesitation.

Matthew Henry Presbyterian @wholebiblehenry

We have here the story of Christ casting the devil out of a child, somewhat more fully related than it was in Mat 17:14, etc. Observe here, I. Christ's return to his disciples, and the perplexity he found them in. He laid aside his robes of glory, and came to look after his family, and to enquire what was become of them.

John Gill Reformed Baptist @doctorgill

And ofttimes it hath cast him into the fire,.... When he has been near it; so that one part or other of his body has been scorched, or burnt, and his life in danger: and into the waters to destroy him: when he has been near any brook, or river, it has thrown him into it, in order to drown him, as into the fire to burn him.
