Numbers 22:7-21 (New International Version)

 ⁷ The elders of Moab and Midian left, taking with them the fee for divination. When they came to Balaam, they told him what Balak had said.

 ⁸ "Spend the night here," Balaam said to them, "and I will bring you back the answer the LORD gives me." So the Moabite princes stayed with him.

 ⁹ God came to Balaam and asked, "Who are these men with you?"

 ¹⁰ Balaam said to God, "Balak son of Zippor, king of Moab, sent me this message: ¹¹ 'A people that has come out of Egypt covers the face of the land. Now come and put a curse on them for me. Perhaps then I will be able to fight them and drive them away.' "

 ¹² But God said to Balaam, "Do not go with them. You must not put a curse on those people, because they are blessed."

 ¹³ The next morning Balaam got up and said to Balak's princes, "Go back to your own country, for the LORD has refused to let me go with you."

 ¹⁴ So the Moabite princes returned to Balak and said, "Balaam refused to come with us."

 ¹⁵ Then Balak sent other princes, more numerous and more distinguished than the first. ¹⁶ They came to Balaam and said:
       "This is what Balak son of Zippor says: Do not let anything keep you from coming to me, ¹⁷ because I will reward you handsomely and do whatever you say. Come and put a curse on these people for me."

 ¹⁸ But Balaam answered them, "Even if Balak gave me his palace filled with silver and gold, I could not do anything great or small to go beyond the command of the LORD my God. ¹⁹ Now stay here tonight as the others did, and I will find out what else the LORD will tell me."

 ²⁰ That night God came to Balaam and said, "Since these men have come to summon you, go with them, but do only what I tell you."

Balaam's Donkey

 ²¹ Balaam got up in the morning, saddled his donkey and went with the princes of Moab.
