Matthew 18

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.

“For where two or three gather in my name, there am I with them.”

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?” Jesus answered, “I tell you, not seven times, but seventy-seven times.”
