"'I will send fire upon Judah that will consume the fortresses of Jerusalem.'" NIV translation
Once again, this prophecy was fulfilled through King Nebuchadnezzar.
"This is what the Lord says: 'For three sins of Israel, even for four, I will not turn back my wrath. They sell the righteous for silver and the needy for a pair of sandals.'" NIV translation
Now, God's focus for judgment turns to the northern kingdom. God begins a list of their sins and it begins with their treatment of the poor. This verse speaks of the fact that the rich would put the poor in bondage to them even for their basic needs.
It seems like this sin is even more widespread in our world today as the gap between rich and poor is wider than ever. This is happening even among people who say they are followers of Jesus Christ.
"They trample on the heads of the poor as upon the dust of the ground and deny justice to the oppressed." NIV translation
The rich of God's people had become so hardened that they did not even see the poor anymore. This is much like our situation in the world today as people simply ignore those around them who are in desperate need. This is even happening among groups of believers (churches) where many in the church have great financial wealth but allow their brothers or sisters in Christ to go hungry. God is telling His people here that they will be judged for this and we should note that God does not change.
"Father and son use the same girl and so profane my holy name. They lie down beside every altar on garments taken in pledge. In the house of their god they drink wine taken as fines." NIV translation
The common man was unimportant and even unseen to a certain degree. The law required that, if a man gave his coat in a pledge, it had to be returned before night but, here, we see that the rich kept the coat and had no regard for the man. It is the same even among the church today as brother will loan to brother and charge interest. The banker is impoverishing the church by lending then money and causing them to be slaves to the almighty dollar. The rich lived it up as pleasure became their god which is much like what we see in the world today.
