ISB ~ Acts 28 v16

to stay by himself:Paul lived for two years under house arrest in Rome. He rented the place at his own expense (28:30), and his wrist was chained at all times to a Roman soldier (28:20).

This living arrangement gave him the freedom to continue limited apostolic work:he evangelized the crowds that gathered around his home (28:23) and wrote his famous “Captivity Epistles” to the Ephesians, the Philippians, the Colossians, and to Philemon.
