John Trapp on 1 Thessalonians 5:19

Verſe 19. Quench not the spirit] In his motions or graces. See he Canon for the fire on the altar, and obſerve it, Lev. 6.12,13. Confeſſe here as Hezekiah did. 2 Chron. 29.6, 7. And take the Apoſtles counſel, 2 Tim. 1.6. Stir up this fire on the hearth of our hearts: let the Prieſts lips blow it up into a flame, deſpiſe not prophecying, &c. It may be quenched either by the with-drawing of fuell (neglect of ordinances) or by caſting on water (falling into foul courſes.)
