'Neck' in the Bible

And whoever is a cause of trouble to one of these little ones who have faith in me, it would be better for him if a great stone was put round his neck and he was dropped into the sea.

And said to them, Go into the little town opposite: and when you come to it, you will see a young ass with a cord round his neck, on which no man has ever been seated; let him loose, and come back with him.
