I recently ran across this nicely presented chiasm for Hebrews 12:1-2 (page 207 of David Alan Black’s Learn To Read New Testament Greek):
A [H]aving SEATED around us such a great cloud of witnesses
>>B SETTING ASIDE every weight and clinging sin
>>>>C with PATIENT ENDURANCE
>>>>>>D let us run the race THAT IS SET BEFORE US
>>>>>>>>E fixing our eyes on Jesus, the author and perfecter of faith
>>>>>>D’ who for the joy THAT WAS SET BEFORE HIM
>>>>C’ PATIENTLY ENDURED the cross
>>B’ SCORNING the shame
A’ and HAS TAKEN HIS SEAT at the right hand of the throne of God
It is not surprising, by the way, to find a chiasm — which is characteristic of ancient Jewish literature — in Hebrews. That book is, of course, likely written by a Jew for Jews, and — to quote another primer (D.H. Hudson, New Testament Greek, in a passage discussing the variation in the Greek across different New Testament books) — “contains the most beautiful language in the New Testament.”
