Chapter 22 in Isaiah is a prophecy against the City of Jerusalem. They were doing things on their own, not once looking to God for help and/or guidance. And so in the Scripture above we see God calling them to repentance, but instead of turning from their sinful ways , they take on a careless and negligent attitude of ‘Let’s eat, drink, and be merry!’ To God it was a dereliction of what they should be doing… showing just how selfish they were and how very little they cared about themselves.
