'People of Israel' in the Bible

Who came with Zerubbabel: Jeshua, Nehemiah, Seraiah, Reelaiah, Mordecai, Bilshan, Mizpar, Bigvai, Rehum, Baanah. The number of the men of the people of Israel:

I make a decree, that all they of the people of Israel, and of his priests and Levites, in my realm, who are disposed of their own free will to go to Jerusalem, go with thee.

Now when these things were done, the princes came to me, saying, The people of Israel, and the priests, and the Levites, have not separated themselves from the people of the lands, doing according to their abominations, even of the Canaanites, the Hittites, the Perizzites, the Jebusites, the Ammonites, the Moabites, the Egyptians, and the Amorites.
