Numbers 23:2-6

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

Then Balaam said to Balak, “Stand beside your burnt offering, and I will go; perhaps the Lord will come to meet me, and whatever He shows me I will tell you.” So he went to a bare hill.

Now God met with Balaam, and he said to Him, “I have set up the seven altars, and I have offered up a bull and a ram on each altar.”

Then the Lord put a word in Balaam’s mouth and said, “Return to Balak, and this is what you shall speak.”

So he returned to him, and behold, he was standing beside his burnt offering, he and all the leaders of Moab.
