1 Chronicles
And for the altar of incense refined gold by weight; and gold for the pattern of the chariot of the cherubims, that spread out their wings, and covered the ark of the covenant of the LORD.
Even three thousand talents of gold, of the gold of Ophir, and seven thousand talents of refined silver, to overlay the walls of the houses withal:
Job

Malachi
And he shall sit as a refiner and purifier of silver: and he shall purify the sons of Levi, and purge them as gold and silver, that they may offer unto the LORD an offering in righteousness.
