(18) Whosoever shall fall upon that stone.--See Note on Matthew 21:44. The verse, which is omitted by many of the best MSS. in St. Matthew, is found in all MSS. of St. Luke. If we were to receive it, on this evidence, as belonging strictly to the latter Gospel only, the Greek word for "bruised" might take its place among those classical, or perhaps quasi-medical, terms characteristic of St. Luke. (See Note on Luke 20:12, and Introduction.)

20:9-19 Christ spake this parable against those who resolved not to own his authority, though the evidence of it was so full. How many resemble the Jews who murdered the prophets and crucified Christ, in their enmity to God, and aversion to his service, desiring to live according to their lusts, without control! Let all who are favoured with God's word, look to it that they make proper use of their advantages. Awful will be the doom, both of those who reject the Son, and of those who profess to reverence Him, yet render not the fruits in due season. Though they could not but own that for such a sin, such a punishment was just, yet they could not bear to hear of it. It is the folly of sinners, that they persevere in sinful ways, though they dread the destruction at the end of those ways.Whosoever shall fall on that stone, shall be broken,.... Not who shall fall upon Christ by faith, and build upon him as the foundation stone, for such shall be saved; but that stumble at him, and are offended with him, and fall by unbelief and hardness of heart; such do themselves much hurt and mischief and expose themselves to danger and ruin; they bid very fair for destruction:

but on whomsoever it shall fall; as it did with its full weight upon the Jews at their destruction, and as it will upon all Christless sinners at the last day:

it will grind him to powder; the ruin of such will be unavoidable, and there will be no recovery; See Gill on Matthew 21:44.
