John Trapp on Jeremiah 6:29

Ver. 29. The bellows are burnt] The Prophets lungs are ſpent,Let us to the wearing of our tongues to the ſtumps preach never ſo much, men will on in ſin. Bradford. Mr. Caſe his Treatiſe of afflictions. all their paines ſpilt upon a perverſe people: See Ezek. 24.6, 12, 13. Jeremy had blowed hard as a Smith or Metallary doth with his bellows; he had ſuffered, as it were, by the heat of a moſt ardent fire, in trying and melting his oar: he had uſed his beſt Art alſo by caſting in lead (as now-adayes they do quick-ſilver) to melt it the more eaſily, and with leſs loſs and waſte: but all to no purpoſe at all.

The lead is conſumed] All the melting judgements which (as lead is caſt into the furnace to make it the hotter) God added to the Miniſtry of the Prophets to make the Word more operative, they will do no good.

The founder melteth in vain] Whether God the Maſter-founder, or the Prophets Gods co-founders or fellow-workmen, as the Apoſtle calleth them, 1 Cor. 6.1.

The wicked are not pluckt away] Or, their wickedneſſes; they will not part with their droſs, or be divorced from their dilecta delicta beloved ſins. The vile perſon will ſpeak villany, and his heart will work iniquity to practiſe hypocriſy, and to utter errour againſt the Lord, Iſa. 32.6.
