Acts 28:14

Where we found brethren, and were desired to tarry with them seven days: and so we went toward Rome.

Cross-reference

Acts 20:6 also records a seven-day stay with believers at Troas — the same duration highlights a pattern in Paul's travels.

In Acts 21:4, Paul stays seven days with disciples in Tyre — a parallel to his seven-day stay with brothers in Puteoli here.
