Jeremiah 6:28 is God’s verdict on the people of Judah: they have become stubborn rebels who spread slander and act corruptly, and their behavior has been tested and found to be base metal rather than pure silver. The prophet Jeremiah speaks these words on God’s behalf, addressing the nation of Judah in the years before Jerusalem fell to Babylon around 586 BC.
They are all grievous rebels, going around to slander. They are brass and iron. All of them deal corruptly.

What Jeremiah 6:28 Means
The verse begins by calling the people “grievous rebels,” meaning persistently defiant against God rather than occasionally mistaken. The phrase “going around to slander” describes a pattern of spreading false or damaging talk about others, which in a close community tears apart trust and justice. Calling them “brass and iron” uses the language of metal to say that what looked like solid, valuable material has proven to be cheap and hard-hearted underneath.
The final line, “All of them deal corruptly,” sums up the charge: their dealings with one another are crooked. The verse does not promise that anyone is beyond God’s reach, and it does not describe every individual in identical terms. It is a judgment on a whole society’s habits, and it leaves room for the reader to ask what faithful living would look like instead.
The Context of Jeremiah 6:28
The book of Jeremiah is traditionally attributed to the prophet himself, who was called by God in the late seventh century BC and preached through the reigns of several kings of Judah. His audience was the people of Jerusalem and the surrounding towns, many of whom trusted in the temple and assumed God would never let the city fall. Jeremiah was often seen as a traitor for urging surrender, which is part of why his words were so unwelcome.
Just before verse 28, God says he has made Jeremiah “a tester of metals,” an image from the refiner’s craft in which the assayer checks ore to see what it is really made of. Verse 29 continues the picture: the bellows blow, the fire burns, and the impurities do not burn away. Read in that setting, verse 28 is the assayer’s report. The verse explains why the refining fails: the metal is brass and iron through and through, so no amount of heat produces pure silver.
