God's jealousy for His glory, shared with His Son

Isaiah 48.11:
For my own sake, for my own sake, I do it,
for how should my name be profaned?
My glory I will not give to another.

God the Father is speaking.  He is jealous for His name (Ex. 20.7f) and His glory.  Consider that He does give His glory to another - His Son, who is co-equal with Him.  Same in essence, three persons. This is just one verse in the argument supporting our understanding of the Trinity.

Compare to passages such as (to name a few):
Jn 7.39
Jn 8.54
Jn 11.4
Jn 12.16
Jn 12.23
Jn 12.28
Jn 13.32
Jn 16.14
Jn 17.5

divine justice in judgement (Dante)

And so the vision granted to your world
can no more fathom Justice Everlasting
then eyes can see down to the ocean floor:

while you can see the bottom near the shore,
you cannot out at sea; but nonetheless
it is still there concealed my depth too deep.
...
for you would say: consider that man born 
along the Indus where you will not find
a soul who speaks or reads or rights of Christ,

and all of his desires, all of his acts
are good, as far as human reason sees;
nor ever having sinned in deed or word,

He dies unbaptized, dies without faith.
What is this justice that condemns his soul? 
What is his guilt if he does not believe?
...
O earthbound creatures! O thick-headed men!
The Primal Will, which of Itself is goodn
never moves from Itself, the Good Supreme.

Only that which accords with it is just.
It is not drawn to any finite good,
but sending forth its rays creates that good.
...
Circling, it sang,  then spoke: even as my notes
are too high for your mind comprehend
so is Eternal Judgment for mankind.

Dante, The Divine Comedy, Paradiso, Canto XI, 58-99.
