Isaiah 43:10-12

New Catholic Bible

¹⁰ You are my witnesses, says the Lord,
    and my servants whom I have chosen,
so that you may know and believe in me
    and understand that it is I.
No god was formed before me,
    nor will there be any after me.
¹¹ I am the Lord,
    and there is no other servant but me.
¹² I have revealed and saved and proclaimed,
    and not some strange god among you;
    you are my witnesses to this, says the Lord.
