'Face of the Earth' in the Bible

and they shall cover the face of the earth, so that one shall not be able to see the earth: and they shall eat the residue of that which is escaped, which remaineth unto you from the hail, and shall eat every tree which groweth for you out of the field:

Wherefore should the Egyptians speak, saying, For evil did he bring them forth, to slay them in the mountains, and to consume them from the face of the earth? Turn from thy fierce wrath, and repent of this evil against thy people.

For wherein now shall it be known that I have found favor in thy sight, I and thy people? is it not in that thou goest with us, so that we are separated, I and thy people, from all the people that are upon the face of the earth?
