Now a certain man drew his bow at random and struck the king of Israel in a joint of the armor. So he said to the driver of his chariot, “Turn around and take me out of the fight; for I am severely wounded.”

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

from whom the whole body, being fitted and held together by what every joint supplies, according to the proper working of each individual part, causes the growth of the body for the building up of itself in love.

and make straight paths for your feet, so that the limb which is lame may not be put out of joint, but rather be healed.
