'Knee' in the Bible

I have sworn by myself; a word that shall not return has gone forth from my mouth [in] righteousness: 'Every knee shall kneel down to me; every tongue shall swear.'

And he measured a thousand [cubits], and he brought me over into the waters [and] [it was] {knee deep}. And he measured a thousand [cubits], and he brought me over [into] the waters [and] [it was] {waist deep}.

But what does the divine response say to him? "I have left for myself seven thousand people who have not bent the knee to Baal."

For it is written, "As I live, says the Lord, every knee will bow to me, and every tongue will praise God."

so that at the name of Jesus every knee should bow, of [those] in heaven and of [those] on earth and of [those] under the earth,
