Nehemiah 10:21 lists Meshezabel, who is identified as the father of Pethahiah in Nehemiah 11:24—a genealogical link.

Genesis 38:30 records the birth of Zerah, the ancestor named here — confirming Pethahiah's lineage from Judah's son Zerah.

Numbers 26:20 lists Zerah as a clan of Judah, showing the tribal structure from which Pethahiah descended.

Matthew 1:3 includes Zerah in Jesus' genealogy, linking this same ancestor to the messianic line.

1 Chronicles 2:4 also names Zerah as son of Judah by Tamar, reinforcing the genealogical record used here.
