To who will every knee bend?

Isaiah 45:21-23 NWT

Make your report, present your case.
Let them consult together in unity.
Who foretold this long ago
And declared it from times past?
Is it not I, Jehovah?
There is no other God but me;
A righteous God and a Savior, there is none besides me.
Turn to me and be saved, all the ends of the earth,
For I am God, and there is no one else.
By myself I have sworn;
The word has gone out of my mouth in righteousness,
And it will not return:
To me every knee will bend,
Every tongue will swear loyalty

Every knee will bend to who?
Romans 14:10-12 NWT

Why do you judge your brother? Or why do you also look down on your brother? For we will all stand before the judgment seat of God. For it is written: ‘As surely as I live,’ says Jehovah, ‘to me every knee will bend, and every tongue will make open acknowledgement to God.’ So, then, each of us will render an account for himself to God.

Every knee will bend to who?
Philippians 2:9-11 NWT

For this very reason, God exalted him to a superior position and kindly gave him the name that is above every other name, so that in the name of Jesus every knee should bend—of those in heaven and those on earth and those under the ground—and every tongue should openly acknowledge that Jesus Christ is Lord to the glory of God the Father.
