But whosoever shall offend one of these little ones who believe in me, it were profitable for him that a great millstone had been hanged upon his neck and he be sunk in the depths of the sea.

And whosoever shall be a snare to one of the little ones who believe in me, it were better for him if a millstone were hung about his neck, and he cast into the sea.

It would be more profitable for him if a millstone were hanged about his neck and he cast into the sea, than that he should be a snare to one of these little ones.

And a strong angel took up a stone, as a great millstone, and cast it into the sea, saying, Thus with violence shall Babylon the great city be cast down, and shall be found no more at all;

and voice of harp-singers and musicians and flute-players and trumpeters shall not be heard any more at all in thee, and no artificer of any art shall be found any more at all in thee, and voice of millstone shall be heard no more at all in thee,
