Numbers 23:25-30

25Then Balak said to Balaam, “Neither curse them at all, nor bless them at all!”

26So Balaam answered and said to Balak, “Did I not tell you, saying, ‘All that the Lord speaks, that I must do’?”

27Then Balak said to Balaam, “Please come, I will take you to another place; perhaps it will please God that you may curse them for me from there.”

28So Balak took Balaam to the top of Peor, that overlooks the wasteland.

29Then Balaam said to Balak, “Build for me here seven altars, and prepare for me here seven bulls and seven rams.”

30And Balak did as Balaam had said, and offered a bull and a ram on every altar.
