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 this in Hebrews. It 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.”
