Numbers 23:4

And God met Balaam: and he said unto him, I have prepared seven altars, and I have offered upon every altar a bullock and a ram.

Cross-reference

In Numbers 23:1, Balaam orders the altars built — the direct preparation that leads to God meeting him in verse 4.

In Numbers 23:16, God again meets Balaam with a word — repeating the pattern of divine encounter after sacrifices.

In Numbers 22:9, God first came to Balaam to question him; here He meets him again after the altars are prepared — another divine visitation.

1 Chronicles 15:26 records sacrificing seven bulls and seven rams — the exact same number and animal types as Balaam's offering.
