Numbers 22:6

22:6 So now, please come and curse this nation for me, for they are too powerful for me. Perhaps I will prevail so that we may conquer them and drive them out of the land. For I know that whoever you bless is blessed, and whoever you curse is cursed.”

Numbers 22:11-12

22:11 “Look, a nation has come out of Egypt, and it covers the face of the earth. Come now and put a curse on them for me; perhaps I will be able to defeat them and drive them out.” 22:12 But God said to Balaam, “You must not go with them; you must not curse the people, for they are blessed.”
