'All Israel' in the Bible

So King Jehoram went forth, on that day, out of Samaria, and numbered all Israel.

Thus did Jehu son of Jehoshaphat son of Nimshi conspire against Joram, - when, Joram, was watching Ramoth-gilead, he and all Israel, because of Hazael king of Syria.

And Jehu sent throughout all Israel, and all the servants of Baal came in, so that there was not left remaining a man, who had not come in, - and they entered the house of Baal, and the house of Baal was filled, from door to door.
