Albert Barnes Commentary Isaiah 43:15

"I am Jehovah, your Holy One, the Creator of Israel, your King." — Isaiah 43:15 (ASV)

I am the Lord — I am Yahweh — proven to be so, as the context requires us to interpret this, by sending to Babylon and bringing down your oppressors. This intervention in destroying Babylon would be a demonstration that He was Yahweh, the only true God, and their God.

The Creator of Israel — (See the note at Isaiah 43:1).

Your King — Ruling over you, and proving His right to do so by delivering you from your enemies.
