18 Therefore hear, ye nations, and know, O assembly, what is among them. 19 Hear, O earth: behold, I will bring evil upon this people, the fruit of their thoughts; for they have not hearkened unto my words, and as to my law, they have rejected it. 20 To what purpose should there come to me incense from Sheba, and the sweet cane from a far country? Your burnt-offerings are not acceptable, nor are your sacrifices pleasing unto me. 21 Therefore thus saith Jehovah: Behold, I will lay stumbling-blocks before this people, and the fathers and the sons together shall fall over them; the neighbour and his friend shall perish. 22 Thus saith Jehovah: Behold, a people cometh from the north country, and a great nation is stirred up from the uttermost parts of the earth. 23 They lay hold on bow and spear; they are cruel, and have no mercy; their voice roareth like the sea; and they ride upon horses, set in array as a man for the battle, against thee, daughter of Zion. 24 We have heard the report thereof: our hands are grown feeble; anguish hath taken hold of us, pain as of a woman that travaileth. 25 Go not forth into the field, nor walk by the way; for [there is] the sword of the enemy, terror is on every side. 26 Daughter of my people, gird thee with sackcloth, and roll thyself in ashes: make mourning, [as] for an only son—bitter lamentation; for the spoiler cometh suddenly upon us. 27 I have set thee among my people as an assayer, a fortress, that thou mayest know and try their way. 28 They are all the most rebellious of rebels, going about with slander: they are bronze and iron; they are all corrupters. 29 The bellows are burned, the lead is consumed by the fire; they have melted, and melted in vain; and the bad are not plucked away. 30 Reprobate silver shall they call them, for Jehovah hath rejected them.

Commentary on Jeremiah 6:18-30

(Read Jeremiah 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.
