Punctuate as follows:
Ezr 8:2. ... of the sons of David, Hattush of the sons of Shechaniah.
Ezr 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 Ezr 8:2-14 occur also as those of heads of families in the list of the Jews who returned with Zerubbabel Ezr 2:3-15. The Septuagint and Syriac versions supply omissions in Ezr 8:5, Ezr 8:10.
