'Knee' in the Bible

And they were smiting him on the head with a reed, and were spitting on him, and having bent the knee, were bowing to him,

but what saith the divine answer to him? 'I left to Myself seven thousand men, who did not bow a knee to Baal.'

for it hath been written, 'I live! saith the Lord -- to Me bow shall every knee, and every tongue shall confess to God;'

that in the name of Jesus every knee may bow -- of heavenlies, and earthlies, and what are under the earth --
