Numbers 22:6-11

6Come now therefore, I pray thee, curse me this people; for they are too mighty for me: peradventure I shall prevail, that we may smite them, and that I may drive them out of the land; for I know that he whom thou blessest is blessed, and he whom thou cursest is cursed.

7And the elders of Moab and the elders of Midian departed with the rewards of divination in their hand; and they came unto Balaam, and spake unto him the words of Balak. 8And he said unto them, Lodge here this night, and I will bring you word again, as Jehovah shall speak unto me: and the princes of Moab abode with Balaam. 9And God came unto Balaam, and said, What men are these with thee? 10And Balaam said unto God, Balak the son of Zippor, king of Moab, hath sent unto me, saying, 11Behold, the people that is come out of Egypt, it covereth the face of the earth: now, come curse me them; peradventure I shall be able to fight against them, and shall drive them out.
