'Precious' in the Bible

Therefore thus says Yahweh, If you return, then will I bring you again, that you may stand before me; and if you take forth the precious from the vile, you shall be as my mouth: they shall return to you, but you shall not return to them.

Moreover I will give all the riches of this city, and all its gains, and all the precious things of it, yes, all the treasures of the kings of Judah will I give into the hand of their enemies; and they shall make them a prey, and take them, and carry them to Babylon.
