Numbers 23:30 DBY

²⁸  And Balak brought Balaam to the top of Peor, which looks over the surface of the waste.

²⁹  And Balaam said to 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 up a bullock and a ram on each altar.
