Isaiah 43:10-12New Revised Standard Version (NRSV)
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.
