Numbers 23:5, 8, 11

The LORD put a word in Balaam’s mouth and said, “Go back to Balak and give him this word.”

How can I curse those whom God has not cursed? How can I denounce those whom the LORD has not denounced?

Balak said to Balaam, “What have you done to me? I brought you to curse my enemies, but you have done nothing but bless them!”
