'Dross' in the Bible

Thou puttest away all the wicked of the earth like dross; therefore I love thy testimonies.

Take away the dross from the silver, and there cometh forth a vessel for the refiner:

Ardent lips, and a wicked heart, are as an earthen vessel overlaid with silver dross.

Thy silver is become dross, thy wine is mixed with water:

And I will turn my hand upon thee, and will thoroughly purge away thy dross, and take away all thine alloy;

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

Therefore thus saith the Lord Jehovah: Because ye are all become dross, therefore behold, I will gather you into the midst of Jerusalem.
