Números 22:6

6 Now come and put a curse on these people, because they are too powerful for me. Perhaps then I will be able to defeat them and drive them out of the land. For I know that whoever you bless is blessed, and whoever you curse is cursed."

6 Come 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.
