It is simple. You have no idea what you are talking about. I do know Hebrew and if YOU knew Hebrew you would understand how the plural works.
A)Elohim, has a plural ending, -im but doesnt not mean more than one. (G-d doesnt contradict himself like you). For example, heaven in in Hebrew, is Shamayim. Are there three heavens? no. Is a description of vastness of heaven.
The same with water- Mayim.
Life- Chayim The face is Panim. Do you have more than one face?
G-d called Moses an Elohim in Exodus 7, is Moses also a god-man?
Judges are are called Elohim. Are they god-men?
The Hebrew word echad work exactly like the word one in english. You can have one set of something or actually one object.
2 Samuel 13:30 And it came to pass, while they were in the way, that tidings came to David, saying, Absalom hath slain all the king's sons, and there is not ONE (echad) of them left.
Eccl 4:8 8 There is ONE (echad) that is alone, and he hath not a second; yea, he hath neither son nor brother; yet is there no end of all his labour......
And Yachid is NOT the word for one. It means unique. The word for One is echad. And G-d calls himself one and never refers to himself as yachid. Why dont you just let G-d describe himself? He makes it abundantly clear.
You are not a fast learner. We have had this discussion before. Why dont you just stop trying to shoe-horn your god-man into G-d. You are no different than a mormon trying to defend his heresy.
Why are you so angry?
You make my point. Water is both singular (water) and plural (waters) simultaneously.
Water is vaporized and less visible. Water can be "incarnated" (embodied) as ice. Such water is plural (vapor; ice; & in most recognized fluidity). But all is water (all same nature; substance).
Thank you for introducing my point.
