Numbers 22:9

Please come now therefore, and curse this people for me; for they are too mighty for me. Perhaps I shall prevail, that we may strike them, and that I may drive them out of the land; for I know that he whom you bless is blessed, and he whom you curse is cursed.”

The elders of Moab and the elders of Midian departed with the rewards of divination in their hand. They came to Balaam, and spoke to him the words of Balak.

He said to them, “Lodge here this night, and I will bring you word again, as the LORD shall speak to me.” The princes of Moab stayed with Balaam.

Balaam said to God, “Balak the son of Zippor, king of Moab, has said to me,

‘Behold, the people that has come out of Egypt covers the surface of the earth. Now, come curse them for me. Perhaps I shall be able to fight against them, and shall drive them out.’”

God said to Balaam, “You shall not go with them. You shall not curse the people, for they are blessed.”
