Numbers 22:5-6

5he 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.

6Please come and put a curse on these people for me because they are more powerful than I am. I may be able to defeat them and drive them out of the land, for I know that those you bless are blessed and those you curse are cursed.”
