Why don’t you try that in the original Hebrew? It’s pretty clear that YHWH is different than Elohim. YHWH is Elohim, but only one Elohim is YHWH.
Jesus’s command in Mark is no different than the word in Deut. You really should look into the doctrine of the Trinity if you’re going to come at me like that.
Come at you? You asked a question and I gave an answer. Saddle on down off that high horse Brother. If I ever 'come at you', and I doubt I ever will, you'll know it.
May the Lord bless you and keep you.
