'Refined' in the Bible

And the king made a great throne of ivory, and overlaid it with refined gold:

and for the altar of incense, refined gold by weight; and the pattern of the chariot of the cherubim of gold, which spread out their wings and cover the ark of the covenant of Jehovah.

three thousand talents of gold, of the gold of Ophir, and seven thousand talents of refined silver, to overlay the walls of the houses;

And in this mountain will Jehovah of hosts make unto all peoples a feast of fat things, a feast of wines on the lees, of fat things full of marrow, of wines on the lees well refined.

Behold, I have refined thee, but not as silver; I have chosen thee in the furnace of affliction.

Many shall be purified, and be made white, and be refined; but the wicked shall do wickedly: and none of the wicked shall understand; but the wise shall understand.

And I will bring the third part into the fire, and will refine them as silver is refined, and will try them as gold is tried. They shall call on my name, and I will answer them: I will say, It is my people; and they shall say, Jehovah is my God.
