ISB ~ 1 Peter 2 v17

the brotherhood:The community of believers united as brothers and sisters in the Lord (5:9).

Honor the emperor:Caesar Nero, who reigned from A.D. 54 to 68 and who launched a savage persecution of Christians after a fire swept through Rome in A.D. 64 (Tacitus, Annals 15, 44). The fact that Peter exhorts readers to honor the emperor in this unqualified way is a strong indication that he is writing before the days of government-sponsored persecution against the Church, which began in the mid-60s and intensified toward the end of the first century. His words would certainly be susceptible to misunderstanding in the late first century when the public display of devotion to the emperor was a life-and-death issue for Christians.
