Numbers 23:18-20

New International Version - UK

‘Arise, Balak, and listen;
    hear me, son of Zippor.
¹⁹ God is not human, that he should lie,
    not a human being, that he should change his mind.
Does he speak and then not act?
    Does he promise and not fulfil?
²⁰ I have received a command to bless;
    he has blessed, and I cannot change it.
