1 Chronicles

1 Chronicles is an impressively long list of literally just names, though it is unique in the Bible for having the added bonus of being a rehash of shit you already slogged through with Samuel. As such, it is credited for being history's first recorded remake.

Authorship
Scholars concluded the Chronicles was definitely written by the prophet Samuel when they decided they didn't want to actually have to study this book.

Historical significance
1 Chronicles is indispensable to historians in its account of the fathering of Nimrod by Cush (1:10). It is also a glimpse into the lives of ancient Israelites and the immense wealth of time they must've had on their hands to write such a book.

Structure
Chronicles has three major sections that you probably could give a shit about.

Contents and interpretation
"'8:17 Zebadiah, Meshullam, Hizki, Heber, 18Ishmerai, Izliah, and Jobab were the sons of Elpaal. 19Jakim, Zichri, Zabdi,  20Elienai, Zillethai, Eliel,  21Adaiah, Beraiah, and Shimrath were the sons of Shimei.' - an excerpt of the exquisite Hebrew prose that pervades 1 Chronicles."Despite the book's infamous tedium, many scholars have gone to great lengths to derive whatever semblance of an interpretation they can from it nonetheless. It is hailed, however, as being an iconic entreatment toward Christian/non-religious unity, as even the staunchest Biblical critics agree that 1 Chronicles is boring as fuck.

Relation to 2 Chronicles
It was first noted that their was a connection between 1 and 2 Chronicles when a researcher at Wadi Qumran unrolled the latter scroll and remarked, "Holy shit, this goes on?" Early Biblical scholars were first clued in to the possible relationship when they noticed that 2 Chronicles begins with this Hebrew phrase,"א  וַיִּתְחַזֵּק שְׁלֹמֹה בֶן-דָּוִיד, עַל-מַלְכוּתוֹ; וַיהוָה אֱלֹהָיו עִמּוֹ, וַיְגַדְּלֵהוּ לְמָעְלָה."which roughly translates to, "But wait, there's more!"

Tradition holds that 1 and 2 Chronicles were originally meant to be one book until a fellow scribe told the author it was "just too fucking long."

Guide to reading
One would do best to adhere to the time-tested Rabbinical tradition of just skipping to Ezra.
