Why Do We Say That?

HIDING YOUR LIGHT UNDER A BUSHEL
A bushel was a container for measuring grain. In Matthew 15:15 Jesus said "Neither do men light a candle and put it under a bushel but on a candlestick."

MOOT POINT
This comes from the Saxon word moot or mote, which meant a meeting to discuss things. A moot point was one that needed to be discussed or debated.

LILY LIVERED
Means cowardly. People once believed that your passions came from your liver. If you were lily livered your liver was white (because it did not contain any blood). So you were a coward.

LICK INTO SHAPE
In the Middle Ages people thought that bear cubs were born shapeless and their mother literally licked them into shape.
