Charles Ellicott 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)

The sons of Shechaniah; Shemaiah. —See Note on 1 Chronicles 1:41.

Hattush. —Probably the Hattush of the sons of David, of the sons of Shechaniah, mentioned by Ezra as one of those who went up with him from Babylon in the second return, 457 B.C. (Ezra 8:2–3). If we have rightly understood 1 Chronicles 3:21, Hattush is of the fourth generation after Zerubbabel (Hananiah, Shechaniah, Shemaiah, Hattush), and so might well have been a youthful companion of Ezra.

Six. —As the text gives only five names, one must have been omitted by an oversight.
