'Four Corners of the Earth' 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.

After this, I saw four angels standing at the four corners of the earth, holding the four winds of the earth, so that no wind would blow on the earth, or on the sea, or on any tree.

and he will come out to deceive the nations which are in the four corners of the earth, Gog and Magog, to gather them together to the war; the number of whom is as the sand of the sea.
