Malachi 3:3

For You have tested us, O God; You have refined us as silver is refined.

The refining pot is for silver and the furnace for gold, But Yahweh tests hearts.

Take away the dross from the silver, And there comes out a vessel for the smith;

“I will also turn My hand against you, And will smelt away your dross as with lye And will remove all your alloy.

Therefore thus says Yahweh of hosts, “Behold, I will refine them and test them; For what else can I do, because of the daughter of My people?

and I will purge from you the rebels and those who transgress against Me; I will bring them out of the land where they sojourn, but they will not enter the land of Israel. Thus you will know that I am Yahweh.

“And some of those who have insight will fall, in order to refine, purge, and make them pure until the time of the end, because it is still to come at the appointed time.

“And I will bring the third part through the fire And refine them as silver is refined And test them as gold is tested. They will call on My name, And I will answer them; I will say, ‘They are My people,’ And they will say, ‘Yahweh is my God.’”

“For behold, the day is coming, burning like a furnace; and all the arrogant and every worker of wickedness will be chaff; and the day that is coming will set them aflame,” says Yahweh of hosts, “so that it will leave them neither root nor branch.”
