Take away the dross from the silver, and material comes out for the refiner;

Like silver dross on an earthen vessel are the lips of a fervent one with an evil heart.

Your silver has become dross, your wine mixed with water.

and I will turn my hand on you, thoroughly purge away your dross, and will take away all your tin.

Son of man, the house of Israel is become dross to me: all of them are brass and tin and iron and lead, in the midst of the furnace; they are the dross of silver.

Therefore thus says the Lord Yahweh: Because you have all become dross, therefore, behold, I will gather you into the midst of Jerusalem.
