Numbers 22:12

לא תלך עמהם THOU SHALT NOT GO WITH THEM — He said: If so, I will curse them in my own place. Whereupon God answered: לא תאור את העם THOU SHALT NOT CURSE THE PEOPLE. — He said to Him: If so, I will bless them. He replied to him: They do not need your blessing, כי ברוך הוא FOR THEY ARE ALREADY BLESSED. A parable! People say to the hornet: neither any of your honey nor any of your sting! (Midrash Tanchuma, Balak 6).

And God said to Bil῾am, Thou shalt not go with them; thou shalt not curse the people: for they are blessed.
