Charles Spurgeon Commentary Jeremiah 31:9-11

"They shall come with weeping; and with supplications will I lead them: I will cause them to walk by rivers of waters, in a straight way wherein they shall not stumble; for I am a father to Israel, and Ephraim is my first-born. Hear the word of Jehovah, O ye nations, and declare it in the isles afar off; and say, He that scattered Israel will gather him, and keep him, as shepherd doth his flock. For Jehovah hath ransomed Jacob, and redeemed him from the hand of him that was stronger than he." — Jeremiah 31:9-11 (ASV)

For I am a father to Israel, and Ephraim is my firstborn. Hear the word of the LORD, O ye nations, and declare it in the isles afar off and say, He that scattered Israel will gather him, and keep him, as a shepherd doth his flock. For the LORD hath redeemed Jacob.

The secret of every other blessing is redemption. If God has redeemed, he will save, depend upon it; the precious blood of Jesus shall never be shed in vain.
