Mark 9:20 Meaning and Commentary

Mark 9:20

And they brought him unto him
The father of the child, and those that were with him, brought the child to Jesus, into his presence, before him:

and when he saw him,
that is, either when Jesus saw the child, or the child saw Jesus; or the evil spirit in him, and by him which were all at once:

straightway the spirit tare him;
threw him into a violent fit, shook him, and convulsed him in a dreadful manner; knowing his time was short, and being filled with indignation and rage, that he should be obliged, as he knew he must, to leave the child very speedily; and was therefore resolved to do all the mischief, and put him to all the pain he could:

and he fell on the ground;
at the feet of Jesus, not being able to stand, through the violent motions and convulsions he threw him into:

and wallowed, foaming;
rolled about from side to side, foaming at the mouth, and in the most exquisite rack and torture.

Mark 9:20 In-Context

20 So they brought the boy. But when the evil spirit saw Jesus, it threw the child into a violent convulsion, and he fell to the ground, writhing and foaming at the mouth.

21 “How long has this been happening?” Jesus asked the boy’s father. He replied, “Since he was a little boy.

22 The spirit often throws him into the fire or into water, trying to kill him. Have mercy on us and help us, if you can.”
