Punctuate as follows:
Ezra 8:2. ... of the sons of David, Hattush of the sons of Shechaniah.
Ezra 8:3. Of the sons of Pharosh, Zechariah ....
Hattush, the descendant of David, was the grandson of Shechaniah (see marginal reference).
Most of these names Ezra 8:2-14 occur also as those of heads of families in the list of the Jews who returned with Zerubbabel Ezra 2:3-15. The Septuagint and Syriac versions supply omissions in Ezra 8:5, Ezra 8:10.
