Omni 1:15 Behold, it came to pass that Mosiah discovered that the people of Zarahemla came out from Jerusalem at the time that Zedekiah, king of Judah, was carried away captive into Babylon.

The people of Zarahemla were descendants of Mulek, the son of Zedekiah, and the people he brought with him. We don't know who they were, and this introduces an interesting element to the book of Mormon: were there any priests or Levites with Mulek? Without any, the Nephites had only the melchezidick priesthood. With some, it is possible that thy had levitical priests. I don't think that it matters, ultimately. The king, Zarahemla himself had no written record of his genealogy, but gave a genealogy of his fathers, according to his memory

On to Zedekiah. We learn about him in Jeremiah 37 1 And king Zedekiah the son of Josiah reigned instead of Coniah the son of Jehoiakim, whom Nebuchadrezzar king of Babylon made king in the land of Judah.
2 But neither he, nor his servants, nor the people of the land, did hearken unto the words of the Lord, which he spake by the prophet Jeremiah. So basically, a wicked king. Also, he was a ak king. The princes hated Jeremiah because he was constantly calling them out on being wicked.

I'd like to revisit this more tomorrow.
