Deuteronomy 32:39-41

New Revised Standard Version, Anglicised Catholic Edition

³⁹ See now that I, even I, am he;
    there is no god besides me.
I kill and I make alive;
    I wound and I heal;
    and no one can deliver from my hand.
⁴⁰ For I lift up my hand to heaven,
    and swear: As I live for ever,
⁴¹ when I whet my flashing sword,
    and my hand takes hold on judgement;
I will take vengeance on my adversaries,
    and will repay those who hate me.
