In Proverbs 1:8-9, it is stated:
 Hear, my son, your father's instruction, and reject not your mother's teaching;  A graceful diadem will they be for your head; a torque for your neck.
But what does a 'torque' refer to? It seems to imply something worn around the neck since the previously described object (diadem) is also worn. And why is it used together with a diadem to refer to a father's instruction and a mother's teaching?
