Suddenly a sword flashed. Bilbo saw it go right through the Great Goblin and he fell dead. Then the sword went back into its sheath.
“Follow me quickly!” said a voice. Dori made Bilbo climb on his shoulders and then they all rushed down dark passages. A pale light was leading them.Of course it was Gandalf; but just then they were too busy to ask how he got there. He took out his sword again, and again it flashed in the dark. This sword’s name was Glamdring the Foe-hammer.
