'All Israel' in the Bible

So Moses and Aaron said to all Israel, “At evening you shall know that the Lord has brought you out of the land of Egypt,

Moses chose able men from all Israel and made them heads over the people, leaders of thousands, of hundreds, of fifties and of tens [from the highest to the lowest judicial levels].

In the breastpiece of judgment you shall put the Urim (Lights) and the Thummim (Perfections) [to be used for determining God’s will in a matter]. They shall be over Aaron’s heart whenever he goes before the Lord, and Aaron shall always carry the judgment (verdict, judicial decisions) of the sons of Israel over his heart before the Lord.
