'All Israel' in the Bible

Thine, O Lord, is the righteousness, but unto us confusion of face, as at this day, to the men of Judah, and to the inhabitants of Jerusalem, and unto all Israel, that are near, and that are far off, in all the countries whither thou hast driven them, because of their unfaithfulness in which they have been unfaithful against thee.

And all Israel have transgressed thy law, even turning aside so as not to listen unto thy voice. And the curse hath been poured out upon us, and the oath that is written in the law of Moses the servant of God: for we have sinned against him.
