Numbers 23:29

New American Standard Bible 2020

And Balaam said to Balak, “Build seven altars for me here and prepare seven bulls and seven rams for me here.”

See the chapter Copy

Because God was helping the Levites who were carrying the ark of the covenant of the Lord, they sacrificed seven bulls and seven rams.

So Balak took Balaam to the top of Peor, which overlooks the desert.

Balak did just as Balaam had said, and offered up a bull and a ram on each altar.
