Numbers 22:7, 17-18

for I will surely do you great honor, and whatever you say to me I will do. Come, curse this people for me.’” But Balaam answered and said to the servants of Balak, “Though Balak were to give me his house full of silver and gold, I could not go beyond the command of the LORD my God to do less or more.
