An adverb meaning 'seventy times'—indicating frequency or repetition. Matthew 18:22 uses it in Jesus' response to Peter's question about forgiveness: not just seven times, but 'seventy times seven' (or 'seventy-seven times' depending on interpretation). Either reading means unlimited forgiveness. The number echoes Genesis 4:24, where Lamech boasts of vengeance seventy-sevenfold—Jesus transforms vengeance into forgiveness. The hyperbolic number isn't meant for literal counting but expresses boundless, inexhaustible grace.
