Numbers 22:15-18

15Then Balak again sent leaders, more numerous and [men who were] more distinguished than the first ones.

16They came to Balaam, and said to him, “Thus says Balak the son of Zippor, ‘I beg you, let nothing hinder you from coming to me.

17For I will give you a very great honor and I will do whatever you tell me; so please come, curse these people [of Israel] for me.’ ”

18Balaam answered 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.
