Isaiah 45:21, 22
Speak up and present your case—yes, let them take counsel together. Who foretold this long ago? Who announced it from ancient times? Was it not I, the LORD? There is no other God but Me, a righteous God and Savior; there is none but Me. / Turn to Me and be saved, all the ends of the earth; for I am God, and there is no other.
Isaiah 59:16
He saw that there was no man; He was amazed that there was no one to intercede. So His own arm brought salvation, and His own righteousness sustained Him.
Acts 4:12
Salvation exists in no one else, for there is no other name under heaven given to men by which we must be saved.”
