Numbers 23:29

²⁷  And Balak said unto Balaam, Come, I pray thee, I will bring thee unto another place; peradventure it will please God that thou mayest curse me them from thence.

²⁸  And Balak brought Balaam unto the top of Peor, that looketh toward Jeshimon.

²⁹  And Balaam said unto Balak, Build me here seven altars, and prepare me here seven bullocks and seven rams.

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