'Face of the Earth' in the Bible

Why should the Egyptians speak and say, He brought them out for harm, to kill them in the mountains and to consume them from the face of the earth? Turn from Your fierce wrath, and be moved to pity as to this evil against Your people.

For in what shall it be known that I and Your people have found grace in Your sight? Is it not in that You go with us? So we shall be separated, I and Your people, from all the people that are upon the face of the earth.
