Numbers 23:11-15

¹¹And Balac said to Balaam, What have you done to me? I called you to curse my enemies, and behold you have greatly blessed them.

¹²And Balaam said to Balac, Whatsoever the Lord shall put into my mouth, shall I not take heed to speak this?

¹³And Balac said to him, Come yet with me to another place where you shall not see the people, but only you shall see a part of them, and shall not see them all; and curse me them from thence.

¹⁴And he took him to a high place of the field to the top of the quarried rock, and he built there seven altars, and offered a calf and a ram on every altar.

¹⁵And Balaam said to Balac, Stand by your sacrifice, and I will go to enquire of God.
