John Trapp on Job 32:19

Verſe 19. Behold my belly is as wine which hath no vent] By this elegant ſimilitude, Elihu illuſtrateth what he had ſaid before; wherein (as Merlin well obſerveth) he compareth words ſhut up in the mind of him, that would faine utter them, to new wine, not yet throughly purged, the ſoul to bottles, ſilence to the ſtopple, which keeps in the wine, grief hereupon to the breaking of thoſe bottles, ſpeech to the opening of them, by taking away the ſtopple of ſilence. And although in this Diſcourſe, Elihu may ſeem to lay on more words then the matter requireth, yet he doth not: for he ſaith no more then the Pſalmiſt doth, Pſal. 45.1. and Jeremiah, chap. 6.11. and the Apoſtles. Act. 4.20. We cannot but ſpeak, &c. And whereas Gregory ſaith, that all this came from pride in Elihu, Chryſoſtom praiſeth him rather (and therein he is in the right) for his zeal, which will have a vent, or the heart will cleave; as the waters undermine, when they cannot overflow. As for that which is urged againſt Elihu, that God ſaith of him, as of a Reprobate and one whom he knew not, Who is this that darkneth counſel by words without knowledg? ch. 38.2. It is plain that God ſpeaketh there, not of Elihu, but of Job. and ſo Job underſtood and applyed it, chap. 42.2. And that God ſpeaketh not of Jobs ſacrificing for him, as for the other three, makes more for his praiſe then elſe; and ſhewes, that he had ſpoken of God the thing that was right, which they had not done, chap. 42.7.
