Numbers 23:27-30

27And Balak said to Balaam, Come, I pray thee, I will bring thee to another place; perhaps it will be right in the sight of 1God that thou curse me them from thence. 28And Balak brought Balaam to the top of Peor, which looks over the surface of the waste. 29And Balaam said to Balak, Build me here seven altars, and prepare me here seven bullocks and seven rams. 30And Balak did as Balaam had said, and offered up a bullock and a ram on each altar.
