'Four' in the Bible

And he will set up an ensign for the nations, and will assemble the outcasts of Israel, and gather together the dispersed of Judah from the four corners of the earth.

Yet there shall be left therein gleanings, as the shaking of an olive-tree, two or three berries in the top of the uppermost bough, four or five in the outmost branches of a fruitful tree, saith Jehovah, the God of Israel.
