In Acts 1:8, Jesus commissions the apostles to be witnesses — the same 'witness' role is given to Paul here.

Acts 4:20 uses the identical phrase 'what we have seen and heard' — the apostles' compulsion to testify mirrors Paul's calling.

Acts 26:20 shows Paul actually carrying out his witness in Damascus, Jerusalem, Judea, and to Gentiles — fulfilling the commission of Acts 22:15.

In Luke 24:48, Jesus says 'You are witnesses of these things' — the same apostolic commission Paul receives, though Paul saw Christ later.

In Revelation 1:2, John bears witness to 'all that he saw,' mirroring the witness role Paul is given in Acts 22:15 to testify of what he has seen and heard.
