Thematic Bible: The lord refining

Awake, O sword, against my shepherd, and against the man that is my fellow, saith the LORD of hosts: smite the shepherd, and the sheep shall be scattered: and I will turn my hand upon the little ones. And it shall come to pass, that in all the land, saith the LORD, two parts therein shall be cut off and die; but the third shall be left therein. And I will bring the third part through 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 hear them: I will say, It is my people; and they shall say, The LORD is my God.

Behold, I will send my messenger, and he shall prepare the way before me: and the Lord, whom ye seek, will suddenly come to his temple, even the messenger of the covenant, whom ye delight in: behold, he will come, saith the LORD of hosts. But who may abide the day of his coming? and who shall stand when he appeareth? for he is like a refiner's fire, and like fuller's soap. 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 to the LORD an offering in righteousness.
