Numbers 23:18-20

Then he took up his discourse and said, “Arise, O Balak, and hear; Give ear to me, O 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? Behold, I have received a command to bless; When He has blessed, then I cannot revoke it.
