כּוּר

But the LORD hath taken you, and brought you forth out of the iron furnace, even out of Egypt, to be unto him a people of inheritance, as ye are this day.

Son of man, the house of Israel is to me become dross: all they are brass, and tin, and iron, and lead, in the midst of the furnace; they are even the dross of silver.

As they gather silver, and brass, and iron, and lead, and tin, into the midst of the furnace, to blow the fire upon it, to melt it; so will I gather you in mine anger and in my fury, and I will leave you there, and melt you.

As silver is melted in the midst of the furnace, so shall ye be melted in the midst thereof; and ye shall know that I the LORD have poured out my fury upon you.

For they be thy people, and thine inheritance, which thou broughtest forth out of Egypt, from the midst of the furnace of iron:

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

Which I commanded your fathers in the day that I brought them forth out of the land of Egypt, from the iron furnace, saying, Obey my voice, and do them, according to all which I command you: so shall ye be my people, and I will be your God:

The fining pot is for silver, and the furnace for gold: but the LORD trieth the hearts.

As the fining pot for silver, and the furnace for gold; so is a man to his praise.
