Acts 28:30-31

And Paul dwelt two whole years in his own hired house, and received all that came in unto him, (31) Preaching the kingdom of God, and teaching those things which concern the Lord Jesus Christ, with all confidence, no man forbidding him.

This was a blessed season to the Church at Rome, which the Lord Jesus granted them. And, from the awful character of the then emperor Nero, under whose cruelty afterwards, both Peter and Paul suffered martyrdom, we can only ascribe it to the Lord Jesus, that he lulled this wretched prince asleep, while Paul thus for two whole years was preaching to the people of God. Supposing, what is generally believed, that Festus detained Paul a year; Felix, we know, confined him two; Acts 24:27, and, here again, two years at Rome; the whole made five. But, it was the Church's mercy, that during the last confinement, he had not only time to preach, but leisure and direction from the Lord, to write those blessed Epistles, which have been made so blessed to the Church, and will be, till time shall be no more. The Epistle to the Ephesians, was evidently written at this time, see Ephesians 3:1, and the date at the end. Colossians also, (Colossians 4:18) and date. To Philemon (Philemon 1:9) and date. Philippians, Philippians 1:16; Philippians 1:16. and date. And, it is more than probable, that it was at the same time he wrote, and sent his Epistles to Galatia and the Hebrews. See the date of each. Some have supposed, that Paul at the end of the two years, was brought to trial, and suffered martyrdom. But this could not be. For his Epistle to Philippi speaks of the confidence he had of being freed, Philippians 1:25 and Philippians 2:16. And his second Epistle to Timothy was written two years after, and is said in the date, to have been written from Rome, when Paul was brought before Nero the second time. And in this Epistle, Paul then speaks of his expectation of death, Acts 4:6.
