Isaiah 43:11

“I, even I, am the Lord, &c.] Jehovah, the self-existing, eternal, and immutable Being; this is doubled for the confirmation of it, and to exclude all others: and besides me there is no Saviour; either in a temporal or spiritual sense; the gods of the Heathens could not save them out of their present troubles, and much less save them with an everlasting salvation; none but God can do this, and this is a proof that Christ is God, since none but God can be a Saviour.”

“Lord--Jehovah. saviour--temporally, from Babylon: eternally, from sin and hell (Hos 13:4; Act 4:12). The same titles as are applied to God are applied to Jesus.”

“I, even I, am the Lord - The repetition of the pronoun ‘I’ makes it emphatic. The design is, to affirm that there was no other being to whom the name ‘Yahweh’ pertained.

“The address now closes by holding up once more the object and warrant of faith. "I am Jehovah; and beside me there is no Savour. I have proclaimed and brought salvation, and given to perceive, and there was no other god among you: and ye are my witnesses, saith Jehovah, and I am God. Even from the day onwards I am so; and there is no deliverer out of my hand: I act, and who can turn it back?" The proper name "Jehovah" is used here ( Isa 43:13) as a name indicating essence: "I and no other am the absolutely existing and living One," i.e., He who proves His existence by His acts, and indeed by His saving acts. מושׁיע and Jehovah are kindred epithets here; just as in the New Testament the name…”
