Luke 20:18

broken,

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).
