Isaiah 43:10-12

New Revised Standard Version Catholic Edition

¹⁰ You are my witnesses, says the Lord,
    and my servant whom I have chosen,
so that you may know and believe me
    and understand that I am he.
Before me no god was formed,
    nor shall there be any after me.
¹¹ I, I am the Lord,
    and besides me there is no savior.
¹² I declared and saved and proclaimed,
    when there was no strange god among you;
    and you are my witnesses, says the Lord.
