Proverbs 17:3

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

"I the LORD search the heart, I try the reins, even to give every man according to his ways, and according to the fruit of his doings."

"Examine me, O LORD, and prove me; try my reins and my heart."

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

"I know also, my God, that thou triest the heart, and hast pleasure in uprightness. As for me, in the uprightness of mine heart I have willingly offered all these things: and now have I seen with joy thy people, which are present here, to offer willingly unto thee."

"That the trial of your faith, being much more precious than of gold that perisheth, though it be tried with fire, might be found unto praise and honour and glory at the appearing of Jesus Christ:"

"For thou, O God, hast proved us: thou hast tried us, as silver is tried."

"And I will kill her children with death; and all the churches shall know that I am he which searcheth the reins and hearts: and I will give unto every one of you according to your works."

"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."
