Numbers 23:18-20

Revised Standard Version Catholic Edition

“Rise, Balak, and hear;
    hearken to me, O son of Zippor:
¹⁹ God is not man, that he should lie,
    or a son of man, that he should repent.
Has he said, and will he not do it?
    Or has he spoken, and will he not fulfil it?
²⁰ Behold, I received a command to bless:
    he has blessed, and I cannot revoke it.
