Ezra 7:4

Now after these things marks a silence of roughly six decades between the temple's dedication in chapter 6 and Ezra's arrival under Artaxerxes, a gap the book does not narrate though the Esther story falls inside it. Ezra's pedigree runs unbroken to Aaron the chief priest, Wesley noting that several generations are omitted for brevity and may be supplied from 1 Chronicles 6. The line matters because Ezra 2:62 has already put priests without a recorded father's house out of the priesthood, so this scribe's credentials stand beyond question before he opens his mouth.
