Hebrews  4:12-13. 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 12 zwn gar o logoV tou qeou 
For the word of God is living 
B kai energhV  and active 
C kai tomwteroV uper pasan macairan distomon 
and sharper than any two-edged sword, 
D kai diiknoumenoV acri merismou yuchV kai pneumatoV 
and piercing as far as the division of soul and spirit, 
E armwn te kai muelwn  of both joints and marrow, 
D* kai kritikoV enqumhsewn kai ennoiwn kardiaV
and able to judge the thoughts and intentions of the heart.
C* 13 kai ouk estin ktisiV afanhV enwpion autou
And there is no creature hidden from His sight, 
B* panta de gumna kai tetrachlismena toiV ofqalmoiV autou 
but all things are open and laid bare to the eyes of Him 
A* proV on hmin o logoV  with whom we have to do.
Note: verses 12-13 are also in the next chiasm
