What does Numbers 22:6 mean?

'Please come and curse these people for me, because they’re too strong for me. Maybe then I’ll be able to defeat them and drive them out. I know that whoever you bless is blessed, and whoever you curse is cursed.' Numbers 22:6 - Modern Text Bible

(Balak wants Balaam to use his spiritual power to curse Israel, believing Balaam’s words have real impact.)
