Matthew 13:41; Matthew 16:23; Matthew 18:7

41 The Son of man shall send forth his angels, and they shall gather out of his kingdom all things that offend, and them which do iniquity;
23 But he turned , and said unto Peter, Get thee behind me, Satan: thou art an offence unto me: for thou savourest not the things that be of God, but those that be of men.
7 Woe unto the world because of offences! for it must needs be that offences come ; but woe to that man by whom the offence cometh !
