Numbers 23:25-29

Then Balak said to Balaam, “Do not curse them at all nor bless them at all!”

But Balaam replied to Balak, “Did I not tell you, ‘Whatever the Lord speaks, I must do’?”

Then Balak said to Balaam, “Please come, I will take you to another place; perhaps it will be agreeable with God that you curse them for me from there.”

So Balak took Balaam to the top of Peor, which overlooks the desert.

And Balaam said to Balak, “Build seven altars for me here and prepare seven bulls and seven rams for me here.”
