'All Israel' in the Bible

So the priests, and the Levites, and the gatekeepers, and the singers, and some of the people, and the Nethinim, and all Israel, dwelt in their cities; and when the seventh month came, the children of Israel were in their cities.

And all Israel in the days of Zerubbabel, and in the days of Nehemiah, gave the portions for the singers and the gatekeepers, every day their portion: and they set apart holy things for the Levites; and the Levites set them apart for the children of Aaron.

Did not Solomon king of Israel sin by these things? yet among many nations was there no king like him, who was beloved of his God, and God made him king over all Israel: nevertheless even him did foreign women cause to sin.
