New Defender's Study Bible Notes
5:1 our reproach. The concluding lamentation is not acrostic in its structure like the others, but it does have twenty-two verses like they do. It expressed both hopelessness and hope in the nature of God and His purpose.
5:16 The crown is fallen. As Jeremiah had prophesied, the crown would pass permanently from the line of King Jehoiachin (Jeconiah), and there would never again be a king in Judah until Messiah would be crowned as king (Jeremiah 22:30; Genesis 49:10; Jeremiah 23:5).
5:19 remainest for ever. God is “from everlasting to everlasting” (Psalm 90:2), and this is the ultimate answer to every question, and solution to every problem.
