Charles Ellicott Commentary Nehemiah 11:4

"And in Jerusalem dwelt certain of the children of Judah, and of the children of Benjamin. Of the children of Judah: Athaiah the son of Uzziah, the son of Zechariah, the son of Amariah, the son of Shephatiah, the son of Mahalalel, of the children of Perez;" — Nehemiah 11:4 (ASV)

Perez. —In 1 Chronicles 9:0 the descendants of Perez (or Phares) are not given; but the descendants of Zerah, present there, are absent here. This may be a question of the right reading of the text.
