Paul was very knowledgeable of all scripture (unlike so many here on TOL) and uses the OT to confirm the deity of Christ.
In this passage from Philippians (particularly verse 10), Paul is referring to the OT about the LORD God.
Php 2:5-11 KJV
(5) Let this mind be in you, which was also in Christ Jesus:
(6) Who, being in the form of God, thought it not robbery to be equal with God:
(7) But made himself of no reputation, and took upon him the form of a servant, and was made in the likeness of men:
(8) And being found in fashion as a man, he humbled himself, and became obedient unto death, even the death of the cross.
(9) Wherefore God also hath highly exalted him, and given him a name which is above every name:
(10) That at the name of Jesus every knee should bow, of things in heaven, and things in earth, and things under the earth;
(11) And that every tongue should confess that Jesus Christ is Lord, to the glory of God the Father.
Here is what Paul was referring to:
Isa 45:21-24 KJV
(21) Tell ye, and bring them near; yea, let them take counsel together: who hath declared this from ancient time? who hath told it from that time? have not I the LORD? and there is no God else beside me; a just God and a Saviour; there is none beside me.
(22) Look unto me, and be ye saved, all the ends of the earth: for I am God, and there is none else.
(23) I have sworn by myself, the word is gone out of my mouth in righteousness, and shall not return, That unto me every knee shall bow, every tongue shall swear.
(24) Surely, shall one say, in the LORD have I righteousness and strength: even to him shall men come; and all that are incensed against him shall be ashamed.
Paul also refers to this same scripture in Romans 14:11 KJV
Rom 14:10-12 KJV
(10) But why dost thou judge thy brother? or why dost thou set at nought thy brother? for we shall all stand before the judgment seat of Christ.
(11) For it is written, As I live, saith the Lord, every knee shall bow to me, and every tongue shall confess to God.
(12) So then every one of us shall give account of himself to God.
So Paul makes it clear that the judgment seat of Christ is the judgment seat of God..
