I've nailed the model Markan chiasm. Here's another example, from Mark 10.
The pattern is typical of Markan chiasms, opening and closing with geographical movement, and having the usual ABBA center. The A brackets contain movement, the B brackets oppose two miniature chiasms built around Jesus/God and last/first. The E brackets both contain messages about leaving everything to follow Jesus, while the F brackets represent another pattern often seen in Mark, where a problem is posed in the first bracket whose solution is expounded in the opposite bracket. Thus How can the rich enter the Kingdom? is solved by observing that with God, all things are possible. The G brackets contain a obvious miniature chiasm that integrates the chreia structure into the chiasm as a whole. The structure of the C/D brackets is flexible and may be collapsed into one bracket.
One thing I like about Mark is the role that chreia structures play in the center of his chiasms.....more to come.
