...What does Sinai say or establish concerning any future king?...
"You shall in any wise set one king over you, whom YHWH your Elohey shall choose:
One From Among Your BROTHERS shall you set KING over you: you may Not set A Stranger over you, Who is Not your Brother.
And he shall not multiply horses to himself, nor cause the people to return to Egypt...
Neither shall he multiply wives to himself....neither shall he greatly multiply to himself silver or gold.
....when he sits on the throne of his kingdom, he will Write him A Copy of this Law in a Book from one which is before the Levi priests:
And it shall be with him, And he Shall Read therein Every Day of his life: that he may learn to stand in awe of YHWH his Elohey, To Keep Every Word of this Law and their statutes, to do them:
That his heart be not lifted up above his brothers, and that he turn not aside from the commandment, to the right hand, or to the left:
to the end that he may prolong his days in his kingdom, he, and his children, in the midst of Israel." [Deuteronomy 17:15-20]
Other than the one case where Moshe, and Aaron failed to Glorify the Rock before the children of Israel, someone alot Like Moshe would fit the above discription of Elohym('s) elect מלאך King;
"...the מלאך Messenger of the Covenant, whom you DELIGHT in..."
"YHWH your Elohey will raise up unto you a Prophet from the midst of you, of your Brothers, Like unto Me; unto him you shall Listen;
According to all that you DESIRED of YHWH your Elohey in Horeb in the day of the assembly, saying, Let me not hear again the Voice of YHWH my Elohey, neither let me see this Great Fire any more, that I die not.
And YHWH said unto me, They have well spoken that which they have spoken.
I will raise them up a Prophet from among their Brothers, LIKE unto YOU, and will put My Words In His Mouth; and he shall speak unto them all that I shall command him.
And it shall come to pass, that whosoever will not listen to my words which he shall speak in my name, I will require it of him." [Deuteronomy 18:15-19]
Have we not all one Father? Did not Elohym create us all? Then to whom will you say, He is not my brother?
"...Who is my mother? and who are my brothers?
He then stretched forth his hand toward his disciples, and said, Behold my mother and my brothers!
For whosoever shall do the will of my Father which is in heaven, the same is my brother, and sister, and mother." [Matthew 12:48-50
Thus the Congregation of Philidelphia is not just a Congregation about (Delphia) Brotherly (Phili) Love, it is also a people who (Phili) Love the (Delphia) Oracle(s) of Yah;
"...If a man love me, he will keep my words.....the word which you hear is not mine, but the Fathers who sent me." [John 14:23-24]
"If a man say, I love Elohym, and hates his brother, he is a liar:..." [1John 4:20]
