Is 77 mentioned in Bible

Answer 1

Yes it is mentioned in Matthew 18:21-22 in the Parable of the Unmerciful Servant. This parable talks about forgiveness of others.

"Then Peter came to Jesus and asked, 'Lord, how many times shall I forgive my brother when he sins against me? Up to seven times?' Jesus answered, 'I tell you, not seven times, but seventy-seven times.'

Although Jesus uses a specific number to show how many times one should forgive another, really by using such a large number he is saying that everyone should always forgive another. Seventy-seven was probably considered a very large number in biblical times.
