Jeremiah 6:28-30

28They have completely turned against God. They refuse to change their minds. They tell lies against people, and they cheat them.

29A very hot fire can remove the dirt from silver and make it pure. I punish my people to make them pure, but it is useless. There are too many wicked people, so I cannot make them pure.

30I, the Lord, cannot accept them, so they are like useless silver.’
