Ye are my witnesses, saith Jehovah, and my servant whom I have chosen; that ye may know and believe me, and understand that I am he: before me there was no God formed, neither shall there be after me. I, even I, am Jehovah; and besides me there is no saviour. I have declared, and I have saved, and I have showed; and there was no strange god among you: therefore ye are my witnesses, saith Jehovah, and I am God. (Isaiah 43:10, ASV)
This verse is one of the few verses in the Bible that does imply a monotheistic view of the Bible as it says that there was no God formed before or after Yahweh. However, if we take this verse very literally we have a problem. Not only does this passage state that there is only one El, it also states that there is only one savior. The Hebrew word for savior is moshiah and is the very same word translated as deliverer in Judges 3:9 where Othniel was the deliverer/savior of Israel (Also see Judges 3:15). From this, we can conclude that Yahweh is the “only savior” figuratively, which then means that Yahweh is the “only Elohim” figuratively.
The main reason that I brought this verse up though is the word "God," which in Hebrew is El (in both occurence), Yahweh is an El. As we have pointed out previously, there are many Elim and apparently, Yahweh is one of them.
