I will bring the third part into the fire, and will refine them as silver is refined, and will test them like gold is tested. They will call on my name, and I will hear them. I will say, 'It is my people;' and they will say, 'The LORD is my God.'"

and he will sit as a refiner and purifier of silver, and he will purify the sons of Levi, and refine them as gold and silver; and they shall offer to the LORD offerings in righteousness.

that the genuineness of your faith, which is more precious than gold that perishes even though it is tested by fire, may be found to result in praise, glory, and honor at the revelation of Jesus Christ?

Beloved, do not be astonished at the fiery trial which has come upon you, to test you, as though a strange thing happened to you.

So

The women sang one to another as they played, and said, "Saul has slain his thousands, David his ten thousands."

Now in all Israel there was none to be so much praised as Absalom for his beauty: from the sole of his foot even to the crown of his head there was no blemish in him.

Absalom did this sort of thing to all Israel who came to the king for judgment. So Absalom stole the hearts of the men of Israel.

General references

The refining pot is for silver, and the furnace for gold, but the LORD tests the hearts.
