Whosoever shall fall on that stone, shall be
 broken,
 &c.] 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).
