Numbers 23:17-19

¹⁷And he came to him, and behold, he was standing by his burnt-offering, and the princes of Moab with him; and Balak said to him, What has Jehovah spoken?

¹⁸Then he took up his parable and said, Rise up, Balak, and hear! hearken unto me, son of Zippor!

¹⁹God is not a man, that he should lie; neither a son of man, that he should repent. Shall he say and not do? and shall he speak and not make it good?
