As “servant” of King Gilgamesh, Enkidu weakens living in the city:The eyes of Enkidu were full of tears and his heart was sick. He sighed bitterly and Gilgamesh met his eye and said, ‘My friend, why do you sigh so bitterly? But Enkidu replied, ‘I am weak, my arms have lost their strength, the cry of sorrow sticks in my throat, I am oppressed by idleness.’
