For thou, O God, hast proved us: thou hast tried us, as silver is tried.
For thou, O God, hast proved us,.... And by the experiment found them to be true and faithful; to have the truth of grace, and the root of the matter in them; not reprobate silver, or their grace counterfeit grace; but of the right kind, solid and substantial;
thou hast tried us as silver is tried; in a furnace, where it is put and melted by the refiner, and purified from the dross that attends it. So the Targum,
"thou hast purified us as the silversmith purifieth the silver;''
or tries it by melting and purifying it. Thus the Lord puts his people into the furnace of afflictions, and sits as a refiner and purifier of them; hereby he tries their graces, faith, patience, hope, and love, their principles and their professions; refines their graces, and makes them more bright and illustrious; removes their dross and tin, and reforms their manners; and proves them to be good silver, and approves of them, and esteems them as such, even as his peculiar treasure. From whence it appears, as well as from the following verses, that afflictions are of God; that they are for the good of his people, and not their hurt; like silver they are put into the fire of affliction, not to be destroyed and lost, but to be purged and refined; and that they are not in wrath, but in love: and this, with what follows, may respect the sufferings of the saints under Rome, Pagan and Papal; when Christ's feet, the members of his mystical body, were like unto fine brass, as if they burned in a furnace; when their graces were tried, their works were known, and their persons proved and approved, Revelation 1:15; see Zechariah 13:9.
