Now Isaiah carries this metaphor forward. What should he do with this wild grape vineyard? He decided to remove the hedges and walls that protected this vineyard from other animals and wild growth. He wanted this vineyard to be devoured and trampled on, so that it would go to waste. He was not going to prune or hoe it. He wanted it to be overgrown with wild briers and thorns. He even was going so far as to command the clouds not to rain on this vineyard. That was a stretch.
This wise person passed by the fields of a lazy person as well as the vineyards of a stupid person. These fields were overgrown with thorns and nettles. The stone wall fences were broken down. Once again, this indicates a strong agricultural society where there were general rules on how to keep up your farming fields. The wise one saw it, looked at it, considered it, and received instructions about it. This un-kept farm field was a big deal.
The hot tempered angry people stir up strife. If you are slow to anger, you can calm contentious situations. The way of the lazy people is overgrown with thorns, but the upright have a nice level highway. Watch your temper! Do not be lazy!
