Numbers 23:1-3, 14, 28

And Balaam said unto Balak, Build me here seven altars, and prepare me here seven oxen and seven rams. And Balak did as Balaam had spoken; and Balak and Balaam offered on every altar a bullock and a ram. And Balaam said unto Balak, Stand by thy burnt offering, and I will go: peradventure the LORD will come to meet me: and whatsoever he sheweth me I will tell thee. And he went to an high place.

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 Balak brought Balaam unto the top of Peor, that looketh toward Jeshimon.
