{Restoration} (apokatastase(9373)). Double compound (apo,
kata, hist(886d)i), here only in the N.T., though common in late
writers. In papyri and inscriptions for repairs to temples and
this phrase occurs in Jewish apocalyptic writings, something like
the new heaven and the new earth of  Re 21:1 . Paul has a
mystical allusion also to the agony of nature in  Ro 8:20-22 .
The verb apokathist(886d)i is used by Jesus of the spiritual and
moral restoration wrought by the Baptist as Elijah ( Mt 17:11  Mr
9:12 ) and by the disciples to Jesus in  Ac 1:6 . Josephus uses
the word of the return from captivity and Philo of the
restitution of inheritances in the year of jubilee. As a
technical medical term it means complete restoration to health.
See a like idea in palingenesia (renewal, new birth) in  Mt
19:28  Tit 3:5 . This universalism of Peter will be clearer to
him after Joppa and Caesarea.
