- See Pérez for the Spanish surname and Peretz for the Jewish name.
According to the Book of Genesis, Pharez/Perez (Hebrew: פֶּרֶץ / פָּרֶץ, Modern Péreẓ / Páreẓ Tiberian Péreṣ / Pāreṣ) was the son of Tamar and Judah, and the twin of Zerah. The name is transliterated to English as both "Perez" (NIV, ESV, NKJV) and "Pharez" (KJV). The Book of Ruth lists Perez as being part of the ancestral genealogy of King David, and the Book of Matthew mentions him when specifying the genealogy of Jesus.
According to biblical scholars, the birth narrative is an etiological myth explaining the origin of parts of the tribe of Judah.
