'Knee' in the Bible

He had him ride in his second chariot; and they proclaimed before him, “Bow the knee!” And he set him over all the land of Egypt.

“I have sworn by Myself,The word has gone forth from My mouth in righteousnessAnd will not turn back,That to Me every knee will bow, every tongue will swear allegiance.

But what is the divine response to him? “I have kept for Myself seven thousand men who have not bowed the knee to Baal.”

For it is written,“As I live, says the Lord, every knee shall bow to Me,And every tongue shall give praise to God.”

so that at the name of Jesus every knee will bow, of those who are in heaven and on earth and under the earth,
