Barking dogs seldom bite.
Beauty is only skin deep.
Beggars can't be choosers.
Better a lean jade than an empty halter.
Better are small fish than an empty dish.
Better be safe than sorry.
Better late than never.
Better the devil you know than the devil you don't know.
Between the hammer and the anvil.
A bird in the hand is worth two in the bush.
A burnt child dreads the fire.
