'People of Israel' in the Bible

Absalom did like this to all of Israel who came to the king for judgment; so Absalom stole the hearts of the people of Israel.

The king went over to Gilgal, and Kimham went over with him. All the people of Judah went over with the king, and half of the people of Israel too.

Then the people of Israel answered the men of Judah and said, "I have {ten times as much} in the king, moreover in David I have more than you. Why did you treat me with contempt {by not giving me first chance} to bring back my king?" But the words of the men of Judah [were] fiercer than the word of the men of Israel.

But the word of the king prevailed over Joab and over the commanders of the army, so Joab and the commanders of the army went out from before the king to count the people of Israel.
