'Knee' in the Bible

For they have abandoned Me; they have bowed the knee to Ashtoreth, the goddess of the Sidonians, to Chemosh, the god of Moab, and to Milcom, the god of the Ammonites. They have not walked in My ways to do what is right in My eyes and to carry out My statutes and My judgments as his father David did.

But I will leave 7,000 in Israel—every knee that has not bowed to Baal and every mouth that has not kissed him.”

By Myself I have sworn;Truth has gone from My mouth,a word that will not be revoked:Every knee will bow to Me,every tongue will swear allegiance.

And when they ask you, ‘Why are you groaning?’ then say: Because of the news that is coming. Every heart will melt, and every hand will become weak. Every spirit will be discouraged, and every knee will turn to water. Yes, it is coming and it will happen.” This is the declaration of the Lord God.
