Bible Verses About Unity of God: His being the only Saviour

Tell ye, and come, and consult together: who hath declared this from the beginning, who hath foretold this from that time? Have not I the Lord, and there is no God else besides me? A just God and a saviour, there is none besides me.

Be converted to me, and you shall be saved, all ye ends of the earth: for I am God, and there is no other.
