Matthew 18
21 Then Peter came and said to him, "Lord, how often shall my brother sin against me, and I forgive him? Until seven times?"
22 Jesus said to him, "I don't tell you until seven times, but, until seventy times seven.
another example:
21 Then Peter came and said to him, "Lord, how often shall my (Wife or Husband) sin against me, and I forgive them? Until seven times?"
22 Jesus said to him, "I don't tell you until seven times, but, until seventy times seven.
Even the sin of Immoralities should be forgiven by the spouse!
