Numbers 22:16-18

16They came to Balaam and said: “This is what Balak son of Zippor says: Do not let anything keep you from coming to me,

17because I will reward you handsomely and do whatever you say. Come and put a curse on these people for me.” 18But Balaam answered them, “Even if Balak gave me all the silver and gold in his palace, I could not do anything great or small to go beyond the command of the LORD my God.
