See now, the Lord, the Lord Almighty, is about to take from Jerusalem and Judah both supply and support; all supplies of food and all supplies of water, the hero and warrior, the judge and prophet, the soothsayer and elder, the captain of fifty and man of rank, the counselor, skilled craftsman and clever enchanter.
In chapter two, we saw how God's people chose to worship the things that they had made and to turn their back on God. Now, Isaiah starts to describe God's answer to this rebellion. The people had forgotten that it was God who sustained them and now they were going to see the effects. Isaiah was basically telling the people that, since they wanted to run their own lives, they were on their own. The same is true of us today as most people are going around ignoring the fact that God created all things and not allowing God to lead them.
