What does Isaiah 3:5 mean?
When leaders are weak and ineffective, a power vacuum forms. Recognizing there will be no consequences for their actions and no protection from others, people will turn on each other to try to provide for their own. The standards for right and wrong in the community will vanish.Isaiah describes that moment coming for Judah when all her strong men and leaders are taken away, leaving only the inexperienced to rule over the people (Isaiah 3:2–4). In response, the people will turn on each other, taking what they can from their neighbors to provide for themselves when resources are scant.
With no strong leaders to hold them accountable, the strong will take advantage of the weak. The young will be disrespectful to the older ones. Those who are despised, or "nobodies" in the NIV, will treat those who should be honored with open disrespect and harshness. The implication here is more than rudeness: Isaiah foresees abuse and manipulation.
The Lord will remove Judah's leaders to show that His people should trust Him first and above all.
