You fool, you have decided to go to the Cedar Forest.
Well, there is no stopping you when your mind's made up, is there, so off you go. You are brave, I'll give you that. Gilgamesh has a dream: the heavens roar, daylight fails and darkness falls, fire blazes out, the clouds lower, and they rain down death. All is turned to ashes. Gilgamesh takes his axe and cuts down a cedar. Humbaba is enraged and cries out, "Who is this that has violated my woods and cut down my cedar?" Gilgamesh is overcome by weakness, for a profound sleep has seized him. Frantically Enkidu tries to rouse him, crying, "O my lord, you do not know this monster and that is the reason you are not afraid. I know him and am terrified. His teeth are dragon's fangs, his countenance like a lion, with his look he crushes alike the trees of the forest and the reeds of the swamp. You can go on, but I am running back to Uruk. I will tell your mother of your glorious death till she weeps for bitterness." But Gilgamesh replies, "Immolation and sacrifice are not yet for me, the boat of the dead shall not go down, nor the cloth be cut for my shrouding. Attack with me, my brother!"
So, together you attack Humbaba. Of course Humbaba will eat you both for breakfast and spit you out for lunch, so you pray to Shamash the Sun, who binds Humbaba for you. I know this is kind of cheating, but what the hey, we won't tell that to the folks back in Uruk, ave? Humbaba begins to cry and says, "I have never known a mother, no, nor a father who reared me. I was born of the mountain, he reared me and made me keeper of the forest. Let me go free and I will be your servant. All the trees I tended will be yours. I will cut them down and build you a palace."
The heart of Gilgamesh is moved with compassion and he cries, "O Enkidu, should not the snared bird return to it's nest and the captive man return to his mother's arms?"
Enkidu replies, "Gilgamesh, the strongest of men will fall to fate if he has no judgment. If the snared bird returns to it's nest, if the captive man returns to his mother's arms, then you my friend will never return to the city where the mother is waiting who gave you birth. Humbaba will bar the mountain road against you, and make the pathways impassable."
Humbaba screams at you, "Enkidu, what you have spoken of is evil: you, a hireling, dependent for your bread! In envy and for fear of a rival you have spoken evil words."
"Do not listen Gilgamesh: this Humbaba must die. Kill Humbaba first and his servants after."
Gilgamesh protests, "Enkidu, if we touch him the blaze and the glory of light will be put out in confusion, the glory and glamour will vanish, its rays will be quenched."
You look at each other and consider each other's words. If you let Humbaba go, it is highly probable that he will kill you both. If you kill him, it will be a shameful act before the gods and not worthy of a great hero such as you yourself are.
