Matthew 18:6-7

18:6 “But if anyone causes one of these little ones who believe in me to sin, it would be better for him to have a huge millstone hung around his neck and to be drowned in the open sea. 18:7 Woe to the world because of stumbling blocks! It is necessary that stumbling blocks come, but woe to the person through whom they come.

Matthew 26:24-25

26:24 The Son of Man will go as it is written about him, but woe to that man by whom the Son of Man is betrayed! It would be better for him if he had never been born.” 26:25 Then Judas, the one who would betray him, said, “Surely not I, Rabbi?” Jesus replied, “You have said it yourself.”
