Paul's situation in Rome 28:16

Paul was a Roman citizen who had appealed to Caesar and had gained the respect (to say the least) of his centurion escort. Therefore he was able to reside in a private rented residence with a Roman guard (v. 30).

This is the end of the last "we"section of Acts (16:10-40; 20:5-21:18; 27:1-28:16). We know that Luke and Aristarchus remained with Paul for some time, and Paul had other visitors including Timothy, Tychicus, and Epaphroditus. Luke and Aristarchus were with him when Paul wrote his epistles to Philemon and to the Colossians (Phile. 24; Col. 4:14), which he composed during his detention in Rome. This imprisonment probably lasted from 60 into 62 A.D. (cf. v. 30).
