'All Israel' in the Bible

So the priests, the Levites, some of the people, the singers, the gatekeepers, and the temple servants settled in their [own] cities, and all Israel [gradually settled] into their cities.

They offered at the dedication of this house of God 100 bulls, 200 rams, 400 lambs, and, as a sin offering for all Israel, 12 male goats, according to the number of Israel’s tribes.

and I weighed out to them the silver, the gold, and the utensils, the offering for the house of our God which the king, his advisers, his officials, and all Israel who were present there had offered.

Also the [former] exiles who had come from the captivity offered burnt offerings to the God of Israel: 12 bulls for all Israel, 96 rams, 77 lambs, and 12 male goats for a sin offering. All this was a burnt offering to the Lord.

Then Ezra stood and made the leaders of the priests, the Levites, and all Israel, take an oath that they would act in accordance with this proposal; so they took the oath.
