All the nations are gathered together, and the peoples are assembled. Who among them can declare this, and tell us the former things? Let them present their witnesses to vindicate [themselves], so that people may hear and say, "It is true."
"You are My witnesses"- the Lord's declaration- "and My servant whom I have chosen, so that you may know and believe Me and understand that I am He. No god was formed before Me, and there will be none after Me.
I, I am the Lord, and there is no other Savior but Me.
I alone declared, saved, and proclaimed- and not some foreign god among you. So you are My witnesses"- the Lord's declaration- "and I am God.
