Baruch opens with a confession of national sin offered by the exiles in Babylon (1:1–3:8), followed by a beautiful wisdom poem identifying Torah with the Wisdom that God alone bestows (3:9–4:4), and a prophetic word of comfort to a personified Jerusalem (4:5–5:9). Chapter 6 — the Letter of Jeremiah — is an extended polemic warning the exiles against the foolishness of Babylonian idols.
Likely a composite work. The KJVA prints the Letter of Jeremiah as Baruch chapter 6; some traditions treat it as a separate book.
Baruch is part of the Apocrypha, so the reader opens in KJVA by default — KJV doesn't include it.
Our cross-reference dataset comes from OpenBible.info (CC-BY) — a community-curated resource that covers the Old and New Testaments only. The Apocrypha isn't yet in their dataset, so we don't have an arc-map for Baruch on this page.
Baruch is still richly connected to the rest of Scripture — the early church quoted it, later writers built on it, and scholarly cross-reference editions (e.g. the Jerusalem Bible, the Nova Vulgata) catalogue those links. We're tracking the gap and will add Apocrypha cross-references when a permissive open dataset becomes available.
