Numbers 23:1, 14, 29

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

So he took him to the field of Zophim on the top of Pisgah, and there he built seven altars and offered a bull and a ram on each altar.

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