Hebrews 12:29-13:6. Chiastic structure copied from Chiastic Analysis of the Epistle to the Hebrews,  arranged by John Bligh (Athenaeum Press, Heythrop College, Oxon, England: 1966). Bligh's work is almost entirely in Greek. For website purposes, I have used unaccented Greek from the Unbound Bible, Nestle-Aland 26, at unbound.biola.edu
I have added English from the New American Standard Bible, revised.

A 29 kai gar o qeoV hmwn pur katanaliskon
for our God is a consuming fire.
B 13:1 h filadelfia menetw  
Let love of the brethren continue.

2 thV filoxeniaV mh epilanqanesqe 
Do not neglect to show hospitality to strangers, 
C dia tauthV gar elaqon tineV xenisanteV aggelouV
for by this some have entertained angels without knowing it.
D 3 mimnhskesqe twn desmiwn 
Remember the prisoners, 

wV sundedemenoi 
as though in prison with them, 
D* twn kakoucoumenwn 
and those who are ill-treated, 

wV kai autoi onteV en swmati
since you yourselves also are in the body.
C* 4 timioV o gamoV en pasin kai h koith amiantoV pornouV gar kai moicouV krinei o qeoV

Marriage is to be held in honor among all, and the marriage bed is to be undefiled; for fornicators and adulterers God will judge.
B* 5 afilarguroV o tropoV arkoumenoi toiV parousin 

Make sure that your character is free from the love of money, being content with what you have; 
A* autoV gar eirhken ou mh se anw oud ou mh se egkatalipw
for He Himself has said, "I will never desert you, nor will I ever forsake you,"

6 wste qarrountaV hmaV legein kurioV emoi bohqoV [kai] ou fobhqhsomai ti poihsei moi anqrwpoV

so that we confidently say, "The Lord is my helper, I will not be afraid. What will man do to me?"
