Numbers 23:14-16

¹⁴And when he had brought him to a high place, upon the top of mount Phasga, Balaam built seven altars, and laying on every one a calf and a ram,

¹⁵He said to Balac: Stand here by thy burnt offering while I go to meet him.

¹⁶And when the Lord had met him, and had put the word in his mouth, he said: Return to Balac, and thus shalt thou say to him.
