⁸ Watch out that you do not lose what we^[a] have worked for, but that you may be rewarded fully.^(A)

³² Remember those earlier days after you had received the light,^(A) when you endured in a great conflict full of suffering.^{(B) 33} Sometimes you were publicly exposed to insult and persecution;^(C) at other times you stood side by side with those who were so treated.^{(D) 34} You suffered along with those in prison^(E) and joyfully accepted the confiscation of your property, because you knew that you yourselves had better and lasting possessions.^{(F) 35} So do not throw away your confidence;^(G) it will be richly rewarded.

²⁴ “But if a righteous person turns^(A) from their righteousness and commits sin and does the same detestable things the wicked person does, will they live?
