'Men of Israel' in the Bible

Now the Philistines fought against Israel. And the men of Israel fled from before the Philistines, and fell down slain in mount Gilboa.

And when all the men of Israel who were in the valley saw that they fled, and that Saul and his sons were dead, they forsook their cities, and fled. And the Philistines came and dwelt in them.

Now when Joab saw that the battle was set against him in front and behind, he chose from all the choice men of Israel, and put them in array against the Syrians.
