Previously, David’s life was different. He was pursued by Saul, escaping from one desert to the other. He lived in caves, fought by himself, and slept on the ground; he did not sin at that time. Later, however, he lived in luxury, in palaces with servants, attendants and slaves. He sent the army to fight, while he stayed in his house on his bed. He stood on the roof and looked at the people. He lacked the desire to be with his fighting army.
