[UntoHim]

I am the LORD: that is my name: and my glory will I not give to another, neither my praise to graven images.
Isaiah 42:8
Septuagint
ἐγὼ κύριος ὁ θεός τοῦτό μού ἐστιν τὸ ὄνομα τὴν δόξαν μου ἑτέρῳ οὐ δώσω οὐδὲ τὰς ἀρετάς μου τοῗς γλυπτοῗς

And now, Father, glorify me in your own presence with the glory that I had with you before the world existed.
John 17:5 ESV
Textus Receptus
καὶ νῦν δόξασόν με σύ πάτερ παρὰ σεαυτῷ τῇ δόξῃ ᾗ εἶχον πρὸ τοῦ τὸν κόσμον εἶναι παρὰ σοί

The most sacred and precious thing to God is his Name. (here in Isaiah: κύριος ὁ θεός - The Lord God) Closely related to his name, and just as sacred and just as precious, is his glory. God will not share his Name with any other, and God will not share his glory with any other.

Moses received the most sacred and most precious gift from God himself - "I AM WHO I AM", and simply "I AM", Later in Exodus Moses exclaimed "Show me your glory!" Moses, along with the Children of Israel, eventually realized that next to his name, the most sacred and most precious thing God could reveal to them was his glory.

Either Jesus Christ was an insane heretic (which is exactly what much of the Jewish leadership thought of him) or he actually shares the glory of God with the Father. He temporarily laid this glory aside from the time of his incarnation until his resurrection, at which time he "reunited" with the Father and resumed his rightful place - sharing in the glory of God with the Father.
