Numbers 23:13-20

Balak said to him, “Come with me, I implore you, to another place from where you can see them, although you will see only the nearest and not all of them; and curse them for me from there.” So he took Balaam to the field of Zophim to the top of [Mount] Pisgah, and built seven altars, and offered a bull and a ram on each altar. Balaam said to Balak, “Stand here beside your burnt offering while I go to meet the LORD over there.” Then the LORD met Balaam and put a speech in his mouth, and said, “Go back to Balak and you shall speak thus.” When Balaam returned to Balak, he was standing beside his burnt offering, and the leaders of Moab were with him. And Balak said to him, “What has the LORD spoken?” Balaam took up his [second] discourse (oracle) and said: “Rise up, O Balak, and hear; Listen [closely] to me, son of Zippor. “God is not a man, that He should lie, Nor a son of man, that He should repent. Has He said, and will He not do it? Or has He spoken and will He not make it good and fulfill it? “Behold, I have received His command to bless [Israel]. He has blessed, and I cannot reverse it.
