Numbers 23:27-30 King James Version (KJV)
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.
