18 Therefore hear, you nations, and know, congregation, what is among them. 19 Hear, earth: behold, I will bring evil on this people, even the fruit of their thoughts, because they have not listened to my words; and as for my law, they have rejected it. 20 To what purpose comes there to me frankincense from Sheba, and the sweet cane from a far country? your burnt offerings are not acceptable, nor your sacrifices pleasing to me. 21 Therefore thus says Yahweh, Behold, I will lay stumbling blocks before this people; and the fathers and the sons together shall stumble against them; the neighbor and his friend shall perish. 22 Thus says Yahweh, Behold, a people comes from the north country; and a great nation shall be 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 roars like the sea, and they ride on horses, everyone set in array, as a man to the battle, against you, daughter of Zion. 24 We have heard its report; our hands wax feeble: anguish has taken hold of us, and pangs as of a woman in travail. 25 Don’t go forth into the field, nor walk by the way; for the sword of the enemy, and terror, are on every side. 26 Daughter of my people, gird yourself with sackcloth, and wallow in ashes! Mourn, as for an only son, most bitter lamentation; for the destroyer shall suddenly come on us. 27 I have made you a tester of metals and a fortress among my people; that you may know and try their way. 28 They are all grievous rebels, going about with slanders; they are brass and iron: they all of them deal corruptly. 29 The bellows blow fiercely; the lead is consumed of the fire: in vain do they go on refining; for the wicked are not plucked away. 30 Men will call them rejected silver, because Yahweh has 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.
