Numbers 23:20

18And he took up his parable, and said, Rise up, Balak, and hear; hearken unto me, thou son of Zippor:

19God is not a man, that he should lie; neither the son of man, that he should repent: hath he said, and shall he not do it? or hath he spoken, and shall he not make it good?

20Behold, I have received commandment to bless: and he hath blessed; and I cannot reverse it.

21He hath not beheld iniquity in Jacob, neither hath he seen perverseness in Israel: the LORD his God is with him, and the shout of a king is among them.

22God brought them out of Egypt; he hath as it were the strength of an unicorn.
