'All Israel' in the Bible

The priests, the Levites, and some of the people lived [in Jerusalem], and the singers, the gatekeepers, and the temple servants [lived] in their cities, and all Israel in their cities.

The exiles that returned from captivity offered burnt offerings to the God of Israel; twelve bulls for all Israel, ninety-six rams, seventy-seven lambs, and twelve goats as a sin offering. All was a burnt offering to Yahweh.
