'All Israel' in the Bible

So the priests, the Levites, the gatekeepers, the singers, some of the people, the temple servants, along with all Israel, lived in their cities.And when the seventh month came, the sons (descendants) of Israel (Jacob) were in their cities.

So in the days of Zerubbabel and [later of] Nehemiah, all Israel would give the daily portions for the singers and the gatekeepers; and they set apart the consecrated portion for the Levites, and the Levites set apart the consecrated portion for the sons of Aaron [the priests].

Did not Solomon king of Israel sin [greatly against God] regarding these things? Yet among the many nations there was no king like him. He was loved by his God, and God made him king over all Israel; nevertheless the foreign women caused even him to sin [by turning to other gods and so, judged by God, he lost his kingdom].
