'Four' in the Bible

And lifting up my eyes I saw four horns.

And the Lord gave me a vision of four metal-workers.

Ho, ho! go in flight from the land of the north, says the Lord: for I have sent you far and wide to the four winds of heaven, says the Lord.

And again lifting up my eyes I saw four war-carriages coming out from between the two mountains; and the mountains were mountains of brass.

And the angel, answering, said to me, These go out to the four winds of heaven from their place before the Lord of all the earth.
