beard the lion, to

To confront a dangerous opponent; to take a risk head- on. The first Book of Samuel (17:35) tells of David, the good shepherd, who pursued a lion that had stolen a lamb and, “when he arose against me, I caught him by his beard, and smote him, and slew him.” The expression often is put, “to beard the lion in his den,” which in effect adds the story of the prophet Daniel, whose enemies had him thrown into a den of lions for the night (Daniel 6:16–24). Daniel survived, saying that God had sent an angel to shut the lions’ mouths. In any event, the term became a Latin proverb, quoted by Horace and Martial and in the Middle Ages by Erasmus, in which a timid hare disdainfully plucked a dead lion’s beard. It began to be used figuratively by the time of Shakespeare, and was a cliché by the mid-nineteenth century.
