Numbers 23:17-19

¹⁷And when he came to him, behold, he stood by his burnt offering, and the princes of Moab with him. And Balak said unto him, What hath the LORD spoken?

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?
