“And he shall sit as a refiner and purifier of silver: and he shall purify the sons of Levi, and purge them as gold and silver, that they may offer unto the LORD an offering in righteousness.”
King James Version (KJV)
3:3 He shall fit - As resolved to attend his work and finish it. He shall purify - The effect of this fiery trial, shall be the thorough cleansing of the persons that are to pass through it. Sons of Levi - Either the Jewish Levites, or all Christians, who are made priests unto God. In righteousness - That they may offer themselves, their souls and bodies to God, in righteousness and true holiness.
