how did jesus's audience understand 'seven' or 'seventy times seven' as a number?

Adds the setting and its conversation across both testaments.

Matthew 18:21-22

“Then Peter came and said to him, "Lord, how often shall my brother sin against me, and I forgive him? Until seven times?" Jesus said to him, "I don't tell you until seven times, but until seventy times seven."”

This passage is from Matthew's Gospel, written in the late 1st century CE, likely for a Jewish-Christian audience. It occurs within a section where Jesus teaches his disciples about community life, humility, and forgiveness, following his parable of the lost sheep.

What does a call to 'unlimited' forgiveness ask of our own understanding of justice and reconciliation in daily life?

Then — the setting

In ancient Israel, the number seven often symbolized completeness or perfection, evident in the seven days of creation or the seven-day festivals. Rabbinic traditions of Jesus's era sometimes suggested a limit to forgiveness, often around three or four times for the same offense, reflecting a practical approach to repeated harm. Peter's suggestion of 'seven times' would have been considered generous in that context, pushing past common custom. Jesus's response, 'seventy times seven' (or 'seventy-seven times' in some interpretations, echoing Genesis 4:24), radically expands this, pointing beyond a calculable limit to an infinite expectation.

Across the Testaments

The Old Testament frequently uses 'seven' to denote completion or sacred cycles, from creation to ritual purity (e.g., Leviticus). 'Seventy' also carries significant weight, such as the seventy nations of the world in Genesis 10 or the seventy years of Babylonian exile. In Genesis 4:24, Lamech's vengeful boast of 'seventy-sevenfold' retribution for an injury stands in stark contrast to Jesus's teaching. Jesus's 'seventy times seven' in the New Testament reinterprets this ancient numerical language, transforming a pattern of escalating retribution into one of boundless reconciliation, thereby fulfilling and transcending earlier understandings of justice.
