Numbers Chapter 23, Verse 19
From BibleWiki
19: God 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?
19: God is not a man, that he should lie, nor is the son of man, that
he should be changed. Hath he said then, and will he not do? hath he
spoken, and will he not fulfil?
19: God is not as man to waver, nor as the son of man to be threatened; shall he say and not perform? shall he speak and not keep [to his word]?
