This truly shows the heart of David. David hated the things that Yahweh hated. He also knew that when a person watches wickedness, it has the ability to 'cling' to us. The Hebrew word that is translated 'cling' is the same Hebrew word that is used to describe a man leaving his father and mother to 'cleave' unto his wife. If not, we should not watch it.
Many movies even have sin written all over their titles as a selling point.
The News Many are the lies of the TV news shows and reporters. Years ago, the media used to report news that was vital to our lives and they still do sometimes. But children of Yahweh should not. We should avoid it. Turn away from it.
