'Four' in the Bible

He will set up a banner 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 gleanings will be left there, like the shaking of an olive tree, two or three olives in the top of the uppermost bough, four or five in the outermost branches of a fruitful tree," says Yahweh, the God of Israel.
