"'Will not all of them taunt him with ridicule and scorn saying, "Woe to him who piles up stolen goods and makes himself wealthy by extortion! How long must this go on?" Will not your debtors suddenly arise? Will they not wake up and make you tremble? Then you will become their victim.'" NIV translation
There is a saying that goes something like: Watch how you climb the ladder of success because you will pass those you crawl over on the way back down. This passage describes the same thing, in that, it talks of the fact that the people that the Babylonians had treated so badly were now going to celebrate the downfall of the Babylonians.
"Because you have plundered many nations, the peoples who are left will plunder you. For you have shed man's blood; you have destroyed lands and cities and everyone in them." NIV translation
There are two reactions that man can have to fear. The first is to cower down and submit; the second is to stand and fight until the end. This verse describes the latter as the Babylonians were so feared that the people who had not been conquered banded together against them. Fear of anything or anyone but God is not of God and therefore has no place in the lives of His people.
If you struggle with fear, then, choose now whether you will cower down and submit to the schemes of the evil one or will stand and fight with the armor that God has provided (see Ephesians 6).
"'Woe to him who builds his realm by unjust gain to set his nest on high, to escape the clutches of ruin!'" NIV translation
This verse speaks to the selfishness of the Babylonians and the fact that they did not care about anyone else. It seems that it could be a warning to our generation as well in that everyone is out for themselves today. Many know that the times are bad and going to get worse so they grab all they can and build themselves a place that they think will shelter them from the evil days that are to come. This can be expected of those that do not know Jesus Christ as their Lord and Savior but many Christians are doing the same things. Our answer to the tough times that are to come is our faith in Jesus Christ not a bunker or a house on a hill.
