Numbers 23:4-6

23:4 Then God met Balaam, who said to him, “I have prepared seven altars, and I have offered on each altar a bull and a ram.” 23:5 Then the Lord put a message in Balaam’s mouth and said, “Return to Balak, and speak what I tell you.”

23:6 So he returned to him, and he was still standing by his burnt offering, he and all the princes of Moab.
