'Neck' in the Bible

“I was [living] at ease, but He crushed me and broke me apart,And He has seized me by the neck and has shaken me to pieces;He has also set me up as His target.

“Have you given the horse his might?Have you clothed his neck with quivering and a shaking mane?

“In Leviathan’s neck resides strength,And dismay and terror dance before him.
