'There is None Besides Me' in the Bible

I - I, am Yahweh, - And there is none besides me ready to save:

that they may know from the rising of the sun, and from the west, that there is none besides me: I am Jehovah, and there is none else.

Declare ye, and bring it forth; yea, let them take counsel together: who hath showed this from ancient time? who hath declared it of old? have not I, Jehovah? and there is no God else besides me, a just God and a Saviour; there is none besides me.
