“Have this mind among yourselves, which is yours in Christ Jesus, who, though he was in the form of God, did not count equality with God a thing to be grasped, but emptied himself, by taking the form of a servant, being born in the likeness of men. And being found in human form, he humbled himself by becoming obedient to the point of death, even death on a cross. Therefore God has highly exalted him and bestowed on him the name that is above every name, so that at the name of Jesus every knee should bow, in heaven and on earth and under the earth, and every tongue confess that Jesus Christ is Lord, to the glory of God the Father” (Philippians 2:5-11).
Following the description of Christ's incarnation and humiliation in vv. 6-8 is the portrayal of his exaltation in vv. 9-11. At the heart of this is the bestowal of "the name which is above every name," to which name every knee will bow and every tongue confess for the glory of God the Father.
But what is this name? Some insist the name is “Jesus.” But most likely it is the name "Lord" (kurios). We should read v. 10 not as telling us that at the name “Jesus” every knee should bow, but rather that at the name which is given to Jesus, the name by which Jesus is known, every knee should bow. And that name is “Lord”! Several things suggest this is correct.
First of all, no name can be more exalted than the name YHWH or Lord. Furthermore, there appears to be a progression in the paragraph to the universal confession that Jesus Christ is LORD (v. 11). In other words, in addition to every other name and title ascribed to Jesus, there is the name of Lord.
But most important of all, verse 10 is a citation of Isaiah 45:23 (vv. 20-25) where the God of Israel is alone worthy of the title Lord. Note carefully the emphasis on monotheism, that there is only one God:
“Assemble yourselves and come; draw near together
