What if you were to use the accepted meaning of elohim from the time of the writings?
The only Elohim Who is without beginning and without end is our Father, however when He used the word in His commandment it was accepted at the time that the meaning is this, "You shall have no mighty ones besides Me."
Since Hebrew does not give capital letters to anything for there are none, it cannot b e proven by this trace,however the then definition does........
Look it up in various sources, and you will find it was applied to men of honor, magistrates, strong men, valorous men etc, and even to those falsely deemed as what we consider a god, that is, an idol.
There is only one true Elohim, and He is the Father, the Son and the Holy Spirit. This is why the plural, Elohim, is employed in this instance and not the singular, el howeer if we do say El it is to God as One, such as on the Cross.
Jesus said my God, my God, or Eli, Eli. The i suffix converts the noun to as having the first person possessive in English before El....my.
