Verse 3. - Mighty things; rather, secret things (literally, inaccessible). It must be admitted that this introduction hardly corresponds to the sequel, which does not contain any special secrets, as we should have thought. Either vers. 2, 3 have been inserted by a later (inspired) editor, whose mind was absorbed in high thoughts of the latter days - for this view may be urged the style and phraseology, which are hardly those of the surrounding chapters, hardly those of Jeremiah; or else we must adopt Hengstenberg's perhaps over subtle suggestion, which, however, does not touch the question of the phraseology, "that throughout Scripture dead knowledge is not regarded as knowledge; that the hope of restoration had, in the natural man, in the prophet, as well as in all believers, an enemy who strove to darken and extinguish it; that therefore it was ever new," or, in the words of Jeremiah, "great and secret things, which thou knowest not."

33:1-13 Those who expect to receive comforts from God, must call upon him. Promises are given, not to do away, but to quicken and encourage prayer. These promises lead us to the gospel of Christ; and in that God has revealed truth to direct us, and peace to make us easy. All who by sanctifying grace are cleansed from the filth of sin, by pardoning mercy are freed from the guilt. When sinners are thus justified, washed, and sanctified in the name of the Lord Jesus, and by the Holy Spirit, they are enabled to walk before God in peace and purity. Many are led to perceive the real difference between the people of God and the world around them, and to fear the Divine wrath. It is promised that the people who were long in sorrow, shall again be filled with joy. Where the Lord gives righteousness and peace, he will give all needful supplies for temporal wants; and all we have will be comforts, as sanctified by the word and by prayer.Call unto me, and I will answer thee,.... This is spoken not to Jerusalem, and the inhabitants of it; but to the prophet, encouraging him to seek the Lord by prayer, promising an answer to him. So the Targum,

"pray before me, and I will receive thy prayer:''

and show thee great and mighty things; or, "fortified ones" (p); which are like fortified cities, that cannot easily be come at, unless the gates are opened to enter into; and designs such as are difficult of understanding, which exceed human belief, and which reason cannot comprehend and take in; and such are the great things of the Gospel. Some copies read it, "things reserved" (q); as the Targum; and so Jarchi, who interprets it of things future, of things reserved in the heart of God, and which he purposed to do; and very rightly:

which thou knowest not; until revealed; and from hence it appears, that by these great and hidden things are not meant the destruction of Jerusalem, and the seventy years' captivity, and return from that, things which Jeremiah had been made acquainted with time after time, and had prophesied of them; but spiritual blessings hereafter mentioned, some of which the deliverance from Babylon were typical of Ben Melech interprets these of comforts great and strong.
