'Joint' in the Bible

When the Man saw that He had not prevailed against Jacob, He touched his hip joint; and Jacob’s hip was dislocated as he wrestled with Him.

I am poured out like water,And all my bones are out of joint.My heart is like wax;It is melted [by anguish] within me.

Like a broken tooth or an unsteady footIs confidence in an unfaithful man in time of trouble.
