Numbers 23:29

American Standard Version (1901)

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

See the chapter Copy

And Balak took Balaam unto the top of Peor, that looketh down upon the desert.

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

And it came to pass, when God helped the Levites that bare the ark of the covenant of Jehovah, that they sacrificed seven bullocks and seven rams.
