(20) He fell on the ground, and wallowed foaming.--Another graphic touch found only in St. Mark.

Verse 20. - And they brought him unto him. The father, it would seem, was not able of himself to bring him, so fierce and violent were the paroxysms of the disorder. And when he saw him, straightway the spirit tare him (συνεσπέραξεν) - it might be rendered, convulsed him - grievously. Observe the Greek construction (καὶ ἰδὼν αὐτὸν τὸ πνεῦμα), masculine participle with neuter noun. The sight of Christ stirred the evil spirit dwelling in the child. He was irritated by the presence of Christ; for he knew his power, and feared lest he should be cast out. Then came the last and most violent convulsion. He wallowed foaming. The word "to wallow" is probably from the Latin volvo. He rolled about in his agony. St. Gregory, quoted by Trench ('Miracles,' p. 397), shows how true all this is to nature; and that "the expulsion of a deadly evil from our spiritual being is not accomplished without a terrible struggle, followed in some cases by extreme prostration."

9:14-29 The father of the suffering youth reflected on the want of power in the disciples; but Christ will have him reckon the disappointment to the want of faith. Very much is promised to our believing. If thou canst believe, it is possible that thy hard heart may be softened, thy spiritual diseases may be cured; and, weak as thou art, thou mayest be able to hold out to the end. Those that complain of unbelief, must look up to Christ for grace to help them against it, and his grace will be sufficient for them. Whom Christ cures, he cures effectually. But Satan is unwilling to be driven from those that have been long his slaves, and, when he cannot deceive or destroy the sinner, he will cause him all the terror that he can. The disciples must not think to do their work always with the same ease; some services call for more than ordinary pains.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.
