Baruch 5:1
1 Take off the garment of your sorrow and affliction, O Jerusalem, and put on forever the beauty of the glory from God. 2 Put on the robe of the righteousness that comes from God; put on your head the diadem of the glory of the Everlasting; 3 for God will show your splendor everywhere under heaven. 4 For God will give you evermore the name, "Righteous Peace, Godly Glory." 5 Arise, O Jerusalem, stand upon the height; look toward the east, and see your children gathered from west and east at the word of the Holy One, rejoicing that God has remembered them.
Ambrose On Repentance 1.9
Rightly, then, is it said: Who shall entreat for him? It implies that it must be such an one as Moses to offer himself for those who sin, or such as Jeremiah, who, though the Lord said to him, Pray not for this people, and yet he prayed and obtained their forgiveness. For at the intercession of the prophet, and the entreaty of so great a seer, the Lord was moved and said to Jerusalem, which had meanwhile repented for its sins, and had said: O Almighty Lord God of Israel, the soul in anguish, and the troubled spirit cries unto You, hear, O Lord, and have mercy. And the Lord bids them lay aside the garments of mourning, and to cease the groanings of repentance, saying: Put off, O Jerusalem, the garment of your mourning and affliction, and clothe yourself in beauty, the glory which God has given you forever.
Notes and References
"... Early exegetes were not only interested in Baruch’s “testimony” to the Son of God, however. Irenaeus quotes a long passage from the poem of consolation, Baruch 4:36–5:9, which he attributes to Jeremiah, in the context of a discussion of the eschatological Jerusalem. Jerome alludes to the same poem, which he attributes correctly to Baruch, as an example of the power of repentance. Ambrose, too, cites Baruch in his work on repentance. (citing Baruch 3:1–2 and 5:1) Clement of Alexandria finds scriptural support in Baruch 3:16–19 (alongside Plato!) for a diatribe against the display of wealth. Basil the Great quotes Baruch 3:3 as testimony to the immutability of God. Methodius quotes Baruch (though he attributes the words to Jeremiah) on two points: Baruch 3:14–15 on the inaccessibility of wisdom, and Baruch 3:24-25 on the incomprehensibility of God. For Augustine, Baruch provides evidence for the existence of giants before the Flood (Baruch 3:26–28). He also cites Baruch 2:31 three times in support of the doctrine of predestination ..."
