'Four' in the Bible

and he will raise a signal for the nations. And he will gather the outcasts of Israel, and he will gather the scattered ones of Judah together from the four {corners} of the earth.

And gleanings will be left over in it, as {when an olive tree is beaten}, two [or] three ripe olive berries in [the] top of a branch, four [or] five on its fruitful branches," {declares} Yahweh, the God of Israel.
