(42-48) Whosoever shall offend.--See Notes on Matthew 18:6-9. The verbal, or all but verbal, reproduction of these verses indicates the impression which they had made on the disciples. It may be noted, however, that St. Mark omits the "Woe unto the world because of offences . . .," which we find in St. Matthew, and that the emphatic thrice-repeated words, "Where their worm dieth not, and the fire is not quenched," are found only in St. Mark. It should be noted, however, that in Mark 9:43; Mark 9:45 the words "into the fire that never shall be quenched" are omitted in some of the best MSS., and that the same MSS., and others, omit both Mark 9:44; Mark 9:46, leaving Mark 9:48 to stand as the only description of Gehenna.

Verse 42. - This verse stands out as the severe antithesis to what has gone before. As he who receives and encourages Christ's little ones and those who are like little children and believe in him, receives him, and so shall receive from him the glorious rewards of Heaven; so, on the contrary, whosoever shall offend one of these little ones that believe in Christ is guilty of deadly sin; and it were better for him if a great millstone (μύλος ὀνικός) - literally, a millstone so large as to require to be turned by an ass - were hanged about his neck, and he were cast into the sea.

9:41-50 It is repeatedly said of the wicked, Their worm dieth not, as well as, The fire is never quenched. Doubtless, remorse of conscience and keen self-reflection are this never-dying worm. Surely it is beyond compare better to undergo all possible pain, hardship, and self-denial here, and to be happy for ever hereafter, than to enjoy all kinds of worldly pleasure for a season, and to be miserable for ever. Like the sacrifices, we must be salted with salt; our corrupt affections must be subdued and mortified by the Holy Spirit. Those that have the salt of grace, must show they have a living principle of grace in their hearts, which works out corrupt dispositions in the soul that would offend God, or our own consciences.And whosoever shall offend one of these little ones that believe in me,.... Whosoever shall do the, least injury to the meanest person that believes in Christ, who are mean both in their own eyes, and the eyes of others; for Christ is not speaking of little children in age, who are neither capable of believing in Christ, nor are they ready to take offence; but of such as belong to him; his disciples and followers, of whom he is speaking in the preceding verse:

it is better for him that a mill stone were hanged about his neck, and he were cast into the sea; and drowned there: the allusion is to the drowning of malefactors, by tying a stone, or any heavy thing about their necks, and casting them into the sea. Casaubon, and others, have shown out of Heathen writers, that this has been a practice of some nations, particularly the Grecians: Jerom says, Christ speaks according to the custom of the country; this being a punishment of the greatest crimes among the Jews; but I have no where met with it in their writings: Christ's sense is, that such who give offence to any of his ministers or people, how mean soever they may appear, shall undergo the severest punishment; See Gill on Matthew 18:6.
