'Four' in the Bible

And he shall lift up a banner to the nations, and shall assemble the outcasts of Israel, and gather together the dispersed of Judah from the four corners of the earth.

And a gleaning shall be left in it, as at the shaking of an olive-tree: two, three berries above, in the tree-top; four, five in its fruitful boughs, saith Jehovah, the God of Israel.
