As for you, O Jacob My servant, do not be afraid, declares the LORD, and do not be dismayed, O Israel. For I will surely save you out of a distant place, your descendants from the land of their captivity! Jacob will return to quiet and ease, with no one to make him afraid.
The Prophet enforces his doctrine by an exhortation; for it would not be sufficient simply to assure us of God’s paternal love and goodwill, unless we were encouraged to hope for it, because experience teaches us how backward and slow we are to embrace the promises of God. This, then, is the reason why the Prophet exhorts and encourages the faithful to entertain hope.
In these verses, as in those foregoing, the deplorable case of the Jews in captivity is set forth, but many precious promises are given them that in due time they should be relieved and a glorious salvation wrought for them. I. God himself appeared against them: he scattered them (Jer 30:11); he did all these things unto them, Jer 30:15.
Commenting on Jeremiah 30:10-17
Therefore fear thou not, O my servant Jacob, saith the Lord,.... Since the Messiah, who is the Lord God, should be raised up to thorn, whom they should serve, and he should save them; and so had nothing to fear from their enemies; and had no reason to doubt of salvation and deliverance, seeing so great a person was engaged for them.
