Identify the speaker and context of the following quotation in Homer's epic.

You have missed your aim, Achilles, peer of the gods, and Jove has not yet revealed to you the hour of my doom, though you made sure that he had done so. You were a false-tongued liar when you deemed that I should forget my valour and quail before you. You shall not drive your spear into the back of a runway-drive it, should heaven so grant your power, drive it into me as I make straight towards you.
