According to any standard Hebrew lexicon the word "one" (echad) is the ordinary counting number “one,” appearing more than 900 times throughout the scriptures.
The word functions just as the word “one” in English. For example, "eleven" in Hebrew is "ten" and echad; Abraham was “echad,” i.e., "Abraham was only one person” (Eze 33:24, NAB, Holman, et al.).
When echad is used with collective nouns like “family” or “bunch,” echad retains its standard meaning, e.g., "one family” not "two families"; "one bunch" not "two bunches.” Any idea of plurality comes from the collective nouns (i.e., family, bunch) and not from the word “one" itself.
Ask yourself, how do you know "one family" is not more than "one"? Well, by the simple fact that the word "one" always retains the meaning of the ordinary counting number.
Again, the word “one" is never plural!
We must not transfer the plurality in the collective noun to the word “one” or, even worse, to the word LORD in the phrase “one LORD."
So, for Trinitarian scholars, linguists, apologists and pastors to do this is misleading to say the least, and at worst deception!
