Numbers 23:16-20

Then the LORD met Balaam, and put a word in his mouth, and said, “Go back to Balak, and thus you shall speak.” So he came to him, and there he was, standing by his burnt offering, and the princes of Moab were with him. And Balak said to him, “What has the LORD spoken?” Then he took up his oracle and said: “Rise up, Balak, and hear! Listen 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? Or has He spoken, and will He not make it good? Behold, I have received a command to bless; He has blessed, and I cannot reverse it.
