Numbers 23:11-15

And Balak said unto Balaam, What hast thou done unto me? I took thee to curse mine enemies, and, behold, thou hast blessed them altogether.

And he answered and said, Must I not take heed to speak that which the LORD hath put in my mouth?

And Balak said unto him, Come, I pray thee, with me unto another place, from whence thou mayest see them: thou shalt see but the utmost part of them, and shalt not see them all: and curse me them from thence.

And he brought him into the field of Zophim, to the top of Pisgah, and built seven altars, and offered a bullock and a ram on every altar.

And he said unto Balak, Stand here by thy burnt offering, while I meet the Lord yonder.
