Numbers 23:4

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

And Balaam said unto Balak, Stand by thy burnt offering, and I will go: peradventure the LORD will come to meet me: and whatsoever he sheweth me I will tell thee. And he went to an high place.

And the LORD put a word in Balaam’s mouth, and said, Return unto Balak, and thus thou shalt speak.

And he returned unto him, and, lo, he stood by his burnt sacrifice, he, and all the princes of Moab.
