And thou shalt remember all the way which Jehovah thy God hath led thee these forty years in the wilderness, that he might humble thee, to prove thee, to know what was in thy heart, whether thou wouldest keep his commandments, or not.

(Let me be weighed in an even balance, That God may know mine integrity);

The refining pot is for silver, and the furnace for gold; But Jehovah trieth the hearts.

And I will bring the third part into 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, Jehovah is my God.

But who can 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:

that the proof of your faith, being more precious than gold that perisheth though it is proved by fire, may be found unto praise and glory and honor at the revelation of Jesus Christ:

Examine me, O Jehovah, and prove me; Try my heart and my mind.
