'Dross' in the Bible

You have removed all the wicked of the earth like dross [for they have no value];Therefore I love Your testimonies.

Take away the dross from the silver,And there comes out [the pure metal for] a vessel for the silversmith [to shape].

Your silver has turned to lead,Your wine is diluted with water.

“And I will turn My hand against you,And will [thoroughly] purge away your dross as with lyeAnd remove all your tin (impurity).

The bellows blow fiercely,The lead is consumed by the fire;In vain they continue refining,But the wicked are not separated and removed.

They call them rejected silver [only dross, without value],Because the Lord has rejected them.

Therefore thus says the Lord of hosts,“Behold, I will refine them [through suffering] and test them;For how else should I deal with the daughter of My people?

“Son of man, the house of Israel has become dross (metallic waste) to Me. All of them are (useless) bronze, tin, iron, and lead in the furnace; they are the dross of silver.
