Numbers 22:15-17 NIV

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 handsomely1 and do whatever you say. Come and put a curse2 on these people for me."
