Perez, also written as Pharez/Peretz (Hebrew: פֶּרֶץ / פָּרֶץ, Modern Pereṣ / Pareṣ Tiberian Péreṣ / Pāreṣ), was the son of Tamar and Judah, and the twin of Zerah, according to the Book of Genesis.[1][2] The twins were conceived after Tamar tricked her father-in-law Judah into having sexual intercourse with her by disguising herself as a prostitute. The name is transliterated to English as both "Perez" (NIV, ESV, NKJV) and "Pharez" (KJV). Perez, in Hebrew means "breach or burst forth" and is named after the narrative of his birth as recorded in Genesis 38:29.[3] According to Ethiopian tradition, Perez became a king of Persia.
