Acts 21:26-30 narrates the incident: Paul purified in the temple, then seized — the basis of his defense here.

Acts 26:21 repeats Paul's claim: Jews seized him in the temple — confirming the same event from his later testimony.

In Acts 21:27, this same purification visit triggered the false accusation of bringing Gentiles into the temple.

Acts 21:28 records the specific charge Paul denies here — that he defiled the temple by bringing Greeks inside.
