'All Israel' in the Bible

He reigned over Judah at Hebron [for] seven years and six months; and he reigned over all Israel and Judah at Jerusalem [for] thirty-three years.

David [was] told, so he gathered all Israel and crossed over the Jordan and came to Helam. Aram {arranged themselves in battle lines} to meet David, and they fought with him.

Then they pitched a tent for Absalom on the roof, and he went [in] to the concubines of his father before the eyes of all Israel.

And he [is] also a {valiant warrior}, whose heart [is] like the heart of the lion. He will {certainly melt} with fear, for all Israel knows that your father [is] a mighty warrior and [those] who [are] with him [are] {valiant warriors}.

[Even] if he withdraws to a city, all Israel will bring up ropes to that city, and they will drag him away to the valley until there [is] not even a pebble to be found."

Then King David sent to Zadok and to Abiathar the priests, saying, "Speak to the elders of Judah: 'Why [are] you last to bring back the king to his house? The talk of all Israel has come to the king in his house.
