Numbers 23:30 YLT

²⁸  And Balak taketh Balaam to the top of Peor, which is looking on the front of the wilderness,

²⁹  and Balaam saith unto Balak, 'Build for me in this 'place' seven altars, and make ready for me in this 'place' seven bullocks and seven rams;'

³⁰  and Balak doth as Balaam said, and he offereth a bullock and a ram on an altar.
