'Surface' in the Bible

he sent messengers to Balaam son of Beor at Pethor, which is by the Euphrates in the land of his people. Balak said to him: “Look, a people has come out of Egypt; they cover the surface of the land and are living right across from me.

‘Look, a people has come out of Egypt, and they cover the surface of the land. Now come and put a curse on them for me. I may be able to fight against them and drive them away.’”
