Numbers 24:10-13

10Then Balak's anger was kindled against Balaam, and he smote his hands together; and Balak said to Balaam, I called thee to curse mine enemies, and behold, thou hast altogether blessed [them] these three times!

11And now flee thou to thy place; I said I would very highly honour thee, and behold, Jehovah has kept thee back from honour.

12And Balaam said to Balak, Did I not also speak to thy messengers whom thou sentest to me, saying,

13If Balak gave me his house full of silver and gold, I could not go beyond the commandment of Jehovah to do good or bad out of my heart: what Jehovah shall say, that will I speak?
