Numbers 23:2

And Balak did as Balaam had spoken; and Balak and Balaam offered on every altar a bullock and a ram.

Cross-references

Numbers 23:14 repeats the action: building seven altars and offering a bullock and a ram on each—a later parallel within the same narrative.

Numbers 23:30 repeats this same sacrificial ritual for the second oracle — identical sequence of bull and ram on each altar.

1 Chronicles 15:26 also records a sacrifice of seven bulls and seven rams — the same number and types as the combined offerings on the seven altars here.
