Jeremiah 20:9 Douay-Rheims

Then I said: I will not make mention of him, nor speak any more in his name: and there came in my heart as a burning fire shut up in my bones, and I was wearied, not being able to bear it.

“For so shall we remain partakers of Christ if we hold fast to the end the Spirit given at the beginning. For he said, "do not quench," not because the Spirit is placed in the power of people and is able to suffer anything from them, but because bad and unthankful people manifestly wish to quench it, since they, like the impure, persecute the Spirit with unholy deeds.… Now they, being without understanding, and deceitful and lovers of sin, walk still as in darkness, not having that "light that lights every one who comes in the world." Now a fire such as this laid hold of Jeremiah the prophet, when the word was in him as a fire and he said, "I leave every place and am not able to endure it." And our Lord Jesus Christ, being good and a lover of humankind, came that he might cast this on earth, and he said, "And would that it were already kindled!"”

“I think, too, we cannot leave out of sight that fire when we read that the Lord Jesus baptizes with the Holy Spirit and with fire, as John said in his Gospel. Rightly was the sacrifice consumed, for it was for sin. But that fire was a type of the Holy Spirit Who was to come down after the Lord's ascension, and forgive the sins of all, and Who like fire inflames the mind and faithful heart. Wherefore Jeremiah, after receiving the Spirit, says: "It became in my heart as a burning fire flaming in my bones, and I am vile and cannot bear it." In the Acts of the Apostles, also, when the Holy Spirit descended upon the apostles and those others who were waiting for the Promise of the Father, we read that tongues as of fire were distributed among them. The soul of each one was so uplifted by His influence that they were supposed to be full of new wine, who instead had received the gift of a diversity of tongues.”

“And thus with greater ardour she raises herself to the very bosom of the Father, wherein is the Only-Begotten Son of God Who declares the secrets of God, which in the time to come are to be revealed face to face. But even now He discloses them partly and in a figure to those whom He deems worthy, and at the same time sheds forth from the Spirit and from His own countenance floods of resplendent light, so that he who is illuminated thereby may say, "But it was as a fire blazing in my bones and I am melted on all sides, and cannot stay." And David says, "Let my sentence come forth from Thy presence!"”

“Jeremiah, having borne many temptations, gave in on these, and when he was rebuked, said, "I will not prophesy, neither will I name the name of the Lord." And David, too, in many places complains of rebuke. Isaiah also, after many things, admonishes concerning this, saying, "Do not fear the reproach of people, neither be overcome by their reviling." And again, Christ also to his disciples: "When they shall speak all manner of evil against you falsely, rejoice and be exceeding glad, for great is your reward in heaven."”

“Here is set forth the prophet's complaint: and first he laments the office enjoined upon him, second the origin of his birth. Concerning the first, two things: first he laments the office enjoined upon him on account of the mockery that followed; second, on account of persecution, at the place, for I have heard the reproaches of many. Concerning the first, three things. First, as if complaining, he makes known the manner of the injunction, "you have deceived"; that is, I received from your words an occasion of deception: for I believed that I would prophesy against the nations, and not against the Jews, from whom I suffer persecution. But he does not mean to impute the crime of deception to God, for that would be blasphemy. "You have prevailed," imposing the office upon me though I resisted, as above, 1. And this especially because he did not see the fruit of his preaching. Isaiah 49: I have labored in vain, without cause and in vain have I spent my strength. Second, he sets forth the outcome of his preaching, setting forth the mockery: "I have become a derision" (...) all of them mock, wrinkling the nose, publishing abroad their derision. Lamentations 3: I have become a derision to all my people, their song all the day. And he assigns the reason, setting forth the word of his preaching, by which he openly rebuked their faults and threatened punishments: for now for a long time I have been crying out, proclaiming iniquity and devastation, which nevertheless has not yet come. Isaiah 16: to those who rejoice over the wall of baked brick, speak their wounds. And the resulting reproach: "and the word of the Lord has become to me a reproach," that is, a cause of reproach. Acts 26: Festus said to Paul: much learning has brought you to madness. Third, he renounces the office enjoined upon him: "and I said." And first he casts off the office: "I will not remember," that is, I will no longer think to speak to the people. For he did not wish to scatter pearls before swine. Matthew 7: do not give what is holy to dogs. Second, he resumes the office he had cast off: "and it became as a fire"; for the more one abstains outwardly from words, the more he feels within the fervor of love. Psalm 38: my heart grew hot within me, and in my meditation a fire shall burn. "In the bones," in the inmost parts of the mind, "I fainted," from my purpose, not enduring to bear the inward burning, "for I have heard the reproaches of many." Here he complains of the office he had undertaken, from the fact that he was enduring persecutions. And first is set forth the persecution of his adversaries: and first he sets forth the multitude of those persecuting him, "of many," against whom resistance is not possible. "Persecute ye"; in which their conspiracy is noted. He also sets forth their familiarity: "from all the men who were at peace with me"; in which the imminent danger is noted. Obadiah: all the men of your covenant have deceived you, the men of your peace have prevailed against you. Second, the prophet's comforting is set forth, setting forth the divine help: "but the Lord is with me," to defend me. Isaiah 50: the Lord God is my helper, and therefore I am not confounded. And his office: "and therefore they shall fall," because they persecute. Isaiah 40: the young shall faint and labor, and the youths shall fall by infirmity. "They shall be confounded," because they have spoken reproaches; "because they did not understand," that is, they were unwilling to understand, the reproach, of eternal damnation, or of future captivity. Psalm 39: let them be confounded, and let them fear who seek my soul to take it away. Third, the petition is set forth: where he seeks to win goodwill, commending justice: "the tester," that is, the approver or examiner and discerner, "of knowledge," who sees the reins, as to the affections, and the hearts, as to the thoughts. Above, 17: I the Lord search the heart, and try the reins, who give to each according to his way, et cetera. He asks for vengeance: "let me see, I beseech you, my vengeance upon them"; he assigns the cause: "for to you have I revealed," not to one ignorant of this, but placing my whole cause in you. Above, 11: for to you have I revealed my cause. Fourth, the giving of thanks is set forth, "sing to the Lord." Psalm 71: for he has delivered the poor from the mighty, the poor man who had no helper.”

“Then I said, I will not make mention of him, nor speak any more in his name,.... Not that he publicly said this before his enemies, or privately to his friends, but he said it in his heart; he thought, nay, resolved, within himself, to prophesy no more; since no credit was given to him, but contempt cast on him; he was disgraced, and God was dishonoured, and no good done; wherefore he concluded it was better to be silent, and not mention the name of God, and say nothing of any message he had from him, since it was to no purpose. A temptation that oftentimes besets a minister of the word, because of the ill usage he meets with, the ill success of his ministry; and is but a temptation, as such see it to be sooner or later, as Jeremiah did; but his word was in mine heart as a burning fire shut up in my bones; which wanted vent, and must have it, and which only could be quenched by being divulged; and which, until it was done, he was in the utmost pain, as if he had been all on fire; his conscience accused him; his heart smote and condemned him; a woe was to him; see Co1 9:16; or "there was in mine heart as a burning fire" (e), &c. a principle of love to God, and to the souls of men; a zeal for his glory, and the good of his countrymen; which made him uneasy, and constrained him to break his former resolution: for the phrase, "his word", is not in the original text; though it is in like manner supplied by the Targum, "and his words became in mine heart as fire burning and overflowing my bones;'' and so Kimchi, "and the word of the Lord was in my heart as fire burning;'' and also Jarchi; the prophecy was as fire, to which it is compared, Jer 23:29; and I was weary with forbearing; to speak; weary to hold it in: and I could not stay; or I could not hold it in any longer; I was obliged to speak in the name of the Lord again, and deliver whatever message he was pleased to send me (e) "atqui est", Junius & Tremellius; "et exstitit", Piscator; "sed factum est in corde meo", Schmidt.”

“his word was--or literally, "there was in my heart, as it were, a burning fire," that is, the divine afflatus or impulse to speak was as . . . (Job 32:18-19; Psa 39:3). weary with forbearing, and I could not--"I labored to contain myself, but I could not" (Act 18:5; compare Jer 23:9; Co1 9:16-17).”
