Matthew 18:6; Matthew 18:7; Matthew 18:15; Matthew 18:21

6 “If anyone causes one of these little ones—those who believe in me—to stumble, it would be better for them to have a large millstone hung around their neck and to be drowned in the depths of the sea.

7 Woe to the world because of the things that cause people to stumble! Such things must come, but woe to the person through whom they come!

15 “If your brother or sister sins, go and point out their fault, just between the two of you. If they listen to you, you have won them over.

21 Then Peter came to Jesus and asked, “Lord, how many times shall I forgive my brother or sister who sins against me? Up to seven times?”
