Albert Barnes Commentary 1 Chronicles 3:22

"And the sons of Shecaniah: Shemaiah. And the sons of Shemaiah: Hattush, and Igal, and Bariah, and Neariah, and Shaphat, six." — 1 Chronicles 3:22 (ASV)

There are only five names in the Hebrew text. The Syriac and Arabic versions supply “Azariah” between Neariah and Shaphat.

The question of the proper arrangement of the genealogy of Zerubbabel’s descendants (1 Chronicles 3:19–24) is important for its bearing on the interesting point of when the Old Testament canon was closed. Assuming an average generation in the East is 20 years, the genealogy in this chapter, according to the Hebrew text, does not extend beyond about 410 B.C. and thus falls within the probable lifetime of Nehemiah.

Furthermore, even if we consider it most probable that Ezra died before 431 B.C. and that this passage was not written entirely by him, this does not disprove the theory that Ezra was the author of Chronicles (see the introduction to Chronicles). Deuteronomy is considered to be by Moses, even though the last chapter could not have been written by his hand. Similarly, the list of the “dukes of Edom” might be an insertion into the text of Genesis (Genesis 36:40–43) without affecting the authorship of the rest of the work.

So it is in this case: Nehemiah or Malachi may have continued the genealogy of the “sons of David” as far as it had reached in their time, adding one or, at most, two verses to the account given by Ezra.
