'All Israel' in the Bible

So the priests, and the Levites, and the porters, and the singers, and some of the people, and the Nethinim, and all Israel, dwelt in their cities. And when the seventh month was come, 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 of the singers and the porters, as every day required: and they set apart that which was for the Levites; and the Levites set apart that which was for the sons of Aaron.

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