The scriptures have something to say about ‘taking a knee’, in fact both knees, and every knee.
11For it is written:
“As I live, says the Lord,
Every knee shall bow to Me,
And every tongue shall confess to God.”
9Therefore God also has highly exalted Him and given Him the name which is above every name, 10that at the name of Jesus every knee should bow, of those in heaven, and of those on earth, and of those under the earth, 11and that every tongue should confess that Jesus Christ is Lord, to the glory of God the Father.
