Numbers 23:18-20

New Revised Standard Version, Anglicised

‘Rise, Balak, and hear;
    listen to me, O son of Zippor:
¹⁹ God is not a human being, that he should lie,
    or a mortal, that he should change his mind.
Has he promised, and will he not do it?
    Has he spoken, and will he not fulfil it?
²⁰ See, I received a command to bless;
    he has blessed, and I cannot revoke it.
