Numbers 23:25-30
25Then Balak said to Balaam, “Do not curse them at all nor bless them at all!” 26But Balaam replied to Balak, “Did I not tell you, saying, ‘aWhatever Yahweh speaks, that I must do’?”
27Then Balak said to Balaam, “Please come, I will take you to another place; perhaps it will be right in the eyes of God that you curse them for me from there.” 28So Balak took Balaam to the top of Peor which overlooks the 1wasteland. 29And Balaam said to Balak, “Build seven altars for me here and prepare seven bulls and seven rams for me here.” 30And Balak did just as Balaam had said and offered up a bull and a ram on each altar.
