MRK 9:42

42 [Jesus also said], “But if you cause someone who believes in me to sin, [God will severely punish you], even if that person is [socially unimportant like] this little child. If someone tied a heavy stone around your neck and you were thrown {and threw you} into the sea, [you would consider that was a severe punishment. But God will punish you more severely] than that [if you cause a person who believes in me to sin].
