Verse 18 describes the arrival of the Assyrian army. The prophet compares the Assyrian hosts to the flies "in the rivers of Egypt", and to the bees in Assyria; that is to say, the invaders will be the innumerable and speedy warriors of the Assyrian king.
The bee symbolizes community, brightness and personal power. Follow the bee to discover your new destination. The ancient Druids saw the bee as symbolising the sun, the Goddess, celebration, and community.
