Numbers 22:5; Numbers 22:6

5 So he sent messengers to Balaam the son of Beor, at Pethor, which is near the River, in the land of the sons of his people, to call him, saying, "Behold, a people came out of Egypt; behold, they cover the surface of the land, and they are living opposite me.

6 "Now, therefore, please come, curse this people for me since they are too mighty for me; perhaps I may be able to defeat them and drive them out of the land. For I know that he whom you bless is blessed, and he whom you curse is cursed."
