Jeremiah 6:29

Therefore thus says Yahweh, “If you return, then I will cause you to return— Before Me you will stand; And if you extract the precious from the worthless, You will become My mouthpiece. They for their part may turn to you, But as for you, you must not turn to them.

“Son of man, the house of Israel has become dross to Me; all of them are bronze and tin and iron and lead in the furnace; they are the dross of silver.

“In your uncleanness is lewdness. Because I would have cleansed you, Yet you are not clean; You will not be cleansed from your uncleanness again Until I have caused My wrath against you to be at rest.
