6:18-30 God rejects their outward services, as worthless to atone for their sins. Sacrifice and incense were to direct them to a Mediator; but when offered to purchase a license to go on in sin, they provoke God. The sins of God's professing people make them an easy prey to their enemies. They dare not show themselves. Saints may rejoice in hope of God's mercies, though they see them only in the promise: sinners must mourn for fear of God's judgments, though they see them only in the threatenings. They are the worst of revolters, and are all corrupters. Sinners soon become tempters. They are compared to ore supposed to have good metal in it, but which proves all dross. Nothing will prevail to part between them and their sins. Reprobate silver shall they be called, useless and worthless. When warnings, corrections, rebukes, and all means of grace, leave men unrenewed, they will be left, as rejected of God, to everlasting misery. Let us pray, then, that we may be refined by the Lord, as silver is refined.

29. bellows … burned—So intense a heat is made that the very bellows are almost set on fire. Rosenmuller translates not so well from a Hebrew root, "pant" or "snort," referring to the sound of the bellows blown hard.

lead—employed to separate the baser metal from the silver, as quicksilver is now used. In other words, the utmost pains have been used to purify Israel in the furnace of affliction, but in vain (Jer 5:3; 1Pe 1:7).

consumed of the fire—In the Chetib, or Hebrew text, the "consumed" is supplied out of the previous "burned." Translating as Rosenmuller, "pant," this will be inadmissible; and the Keri (Hebrew Margin) division of the Hebrew words will have to be read, to get "is consumed of the fire." This is an argument for the translation, "are burned."

founder—the refiner.

wicked … not plucked away—answering to the dross which has no good metal to be separated, the mass being all dross.
