'All Israel' in the Bible

All these warriors arrived in battle order at Hebron, fully intending to establish David as king over all Israel. Furthermore, all of the rest of Israel were united in their intent to make David king.

The next day, they offered sacrifices and burnt offerings to the LORD amounting to 1,000 bulls, 1,000 rams, and 1,000 lambs, along with their libations. Sacrifices were abundant throughout all Israel,

and the LORD exalted Solomon magnificently in the sight of all Israel, bestowing upon him royal majesty such as had not been given to any king in Israel before him.
