Peter went up to Jesus and asked “Teacher, how many times should I forgive someone who sins against me? As many as seven times?”

MT 18:21

“Listen to me closely,” Jesus said. “Don’t forgive him seven times, but seventy times seven! If he offends you seven times in one day, yet comes back to you seven times saying that he repents, you must forgive him.”

MT 18:22, LK 17:3-4
