Luke 17:1-2

AND [Jesus] said to His disciples, Temptations (snares, traps set to entice to sin) are sure to come, but woe to him by or through whom they come! It would be more profitable for him if a millstone were hung around his neck and he were hurled into the sea than that he should cause to sin or be a snare to one of these little ones [lowly in rank or influence].
