Numbers 23:18-20

Then Balaam gave this message: “Stand up, Balak, and listen. Hear me, son of Zippor. God is not a human being, and he will not lie. He is not a human, and he does not change his mind. What he says he will do, he does. What he promises, he makes come true. He told me to bless them, so I cannot change the blessing.
