Numbers 22:14-18

And the representatives from Moab got up and went to Balak, and said, “Balaam refused to come with us.”

Then Balak sent representatives once again, more numerous and more distinguished than the previous.

They came to Balaam and said to him, “This is what Balak the son of Zippor says: ‘I beg you, let nothing keep you from coming to me;

for I will indeed honor you richly, and I will do whatever you tell me. Please come then, curse this people for me.’ ”

But Balaam replied to the servants of Balak, “Even if Balak were to give me his house full of silver and gold, I could not do anything, either small or great, contrary to the command of the Lord my God.
