Hebrews 12:11-17. 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 11 pasa de paideia proV men to paron ou dokei caraV einai alla luphV 
All discipline for the moment seems not to be joyful, but sorrowful; 
B usteron de karpon eirhnikon toiV di authV gegumnasmenoiV apodidwsin dikaiosunhV

yet to those who have been trained by it, afterwards it yields the peaceful fruit of righteousness.
C 12 dio taV pareimenaV ceiraV kai ta paralelumena gonata anorqwsate

Therefore, strengthen the hands that are weak and the knees that are feeble,

13 kai trociaV orqaV poieite toiV posin umwn ina mh to cwlon ektraph iaqh de mallon

and make straight paths for your feet, so that the limb which is lame may not be put out of joint, but rather be healed.
D 14 eirhnhn diwkete meta pantwn 

Pursue peace with all men, 
E kai ton agiasmon ou cwriV oudeiV oyetai ton kurion
and the sanctification without which no one will see the Lord.
D* 15 episkopounteV 

See to it 
C* mh tiV usterwn apo thV caritoV tou qeou mh tiV riza pikriaV anw fuousa enoclh kai di authV mianqwsin polloi

that no one comes short of the grace of God; that no root of bitterness springing up causes trouble, and by it many be defiled;

16 mh tiV pornoV h bebhloV wV hsau oV anti brwsewV miaV apedeto ta prwtotokia eautou

that there be no immoral or godless person like Esau, who sold his own birthright for a single meal.

Hebrews 12:17
iste gar oti kai
For you know that even 
B* metepeita qelwn klhronomhsai thn eulogian apedokimasqh 
afterwards, when he desired to inherit the blessing, he was rejected, 
A* metanoiaV gar topon ouc euren kaiper meta dakruwn ekzhthsaV authn
for he found no place for repentance, though he sought for it with tears.
