30:1-11 Jeremiah is to write what God had spoken to him. The very words are such as the Holy Ghost teaches. These are the words God ordered to be written; and promises written by his order, are truly his word. He must write a description of the trouble the people were now in, and were likely to be in. A happy end should be put to these calamities. Though the afflictions of the church may last long, they shall not last always. The Jews shall be restored again. They shall obey, or hearken to the Messiah, the Christ, the Son of David, their King. The deliverance of the Jews from Babylon, is pointed out in the prophecy, but the restoration and happy state of Israel and Judah, when converted to Christ their King, are foretold; also the miseries of the nations before the coming of Christ. All men must honour the Son as they honour the Father, and come into the service and worship of God by him. Our gracious Lord pardons the sins of the believer, and breaks off the yoke of sin and Satan, that he may serve God without fear, in righteousness and true holiness before him all the remainder of his days, as the redeemed subject of Christ our King.

5. We have heard … trembling—God introduces the Jews speaking that which they will be reduced to at last in spite of their stubbornness. Threat and promise are combined: the former briefly; namely, the misery of the Jews in the Babylonian captivity down to their "trembling" and "fear" arising from the approach of the Medo-Persian army of Cyrus against Babylon; the promise is more fully dwelt on; namely, their "trembling" will issue in a deliverance as speedy as is the transition from a woman's labor pangs to her joy at giving birth to a child (Jer 30:6).
