'Face of the Earth' in the Bible

Why should the Egyptians speak, and say, For misfortune he has brought them out, to slay them on the mountains, and to annihilate them from the face of the earth? Turn from the heat of thine anger, and repent of this evil against thy people!

And how shall it be known then that I have found grace in thine eyes I and thy people? Is it not by thy going with us? so shall we be distinguished, I and thy people, from every people that is on the face of the earth.
