Acts 26:22 states Paul testifies only what the prophets said — grounding the appeal to Agrippa's belief in those same prophets.

Acts 26:23 specifies the prophets' message: Christ's suffering and resurrection — the content of what Agrippa is asked to believe.

In Acts 24:14, Paul similarly affirms his belief in the Law and the Prophets, reinforcing his consistent testimony.

John 5:39 has Jesus saying the Scriptures testify of him — the same prophets Agrippa is asked to believe point to Christ.
