'Four' in the Bible

And he will put up a flag as a sign to the nations, and he will get together those of Israel who had been sent away, and the wandering ones of Judah, from the four ends of the earth.

But it will be like a man shaking an olive-tree, something will still be there, two or three berries on the top of the highest branch, four or five on the outside branches of a fertile tree, says the Lord, the God of Israel.
