Numbers 23:1-3, 14, 28

Balaam said, “Build me seven altars here, and prepare seven bulls and seven rams for me.” Balak did as Balaam said, and the two of them offered a bull and a ram on each altar. Then Balaam said to Balak, “Stay here beside your offering while I go aside. Perhaps the LORD will come to meet with me. Whatever he reveals to me I will tell you.” Then he went off to a barren height.

So he took him to the field of Zophim on the top of Pisgah, and there he built seven altars and offered a bull and a ram on each altar.

And Balak took Balaam to the top of Peor, overlooking the wasteland.
