Idleness was the number one problem in David’s case, if he was in the front line he won’t be messing with someone’s wife. He really did Uriah dirty, among all the women he could have, David’s decided it was one of his loyal soldiers wife he decided to have. While plotting to kill Uriah he also sacrificed a couple of other soldiers with him…that was low low. It looked like David generally had a thing for people’s wives.
