Why did LXX divide the Hebrew Book of Kings into First and Second Kings?

[tonychanyt]

FreeBibleCommentary:

Like I & II Samuel and I & II Chronicles, I & II Kings was first divided into two books by the LXX. Apparently, this was done because of the length of these books. They simply would not fit on one parchment scroll because of the weight and bulk of the leather.

Hebrew writings without the vowels were shorter than Greek which had vowels. The Greek translations took up more space. For practical reasons, LXX divided these Hebrew books at the sensible spots in the timeline.
