Isaiah 43:10-12 Revised Standard Version Catholic Edition (RSVCE)
10 “You are my witnesses,” says the Lord,
“and my servant whom I have chosen,
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.
