Observe here, I. The date of this comfortable prophecy which God entrusted Jeremiah with. It is not exact in the time, only that it was after that in the foregoing chapter, when things were still growing worse and worse; it was the second time. God speaketh once, yea, twice, for the encouragement of his people. We are not only so disobedient that we have need of precept upon precept to bring us to our duty, but so distrustful that we have need of promise upon promise to bring us to our comfort. This word, as the former, came to Jeremiah when he was in prison. Note, No confinement can deprive God's people of his presence; no locks nor bars can shut out his gracious visits; nay, oftentimes as their afflictions abound their consolations much more abound, and they have the most reviving communications of his favour when the world frowns upon them. Paul's sweetest epistles were those that bore date out of a prison.
