ἑπτάκις

And if he trespass against thee seven times in a day, and seven times in a day turn again to thee, saying, I repent; thou shalt forgive him.

Then came Peter to him, and said, Lord, how oft shall my brother sin against me, and I forgive him? till seven times?

Jesus saith unto him, I say not unto thee, Until seven times: but, Until seventy times seven.
