Who was Zarah?

Zarah (also spelled Zerah in some translations) was one of the twin sons born to Judah and Tamar, as recorded in Genesis 38:27-30. His Hebrew name זֶרַח (Zeraḥ) means “rising,” “shining,” or “brightness”, which likely reflects the circumstances of his birth or points symbolically to dawn or new light.

Zarah’s birth is particularly notable due to the unusual and dramatic nature of the labor, which involved a struggle between him and his twin brother Perez. Though Zarah’s hand emerged first and was marked with a scarlet thread, it was Perez who ultimately came out of the womb first, gaining precedence. This reversal of expected birth order is central to the narrative and rich in theological significance.

The Story of Zarah in the Bible

In Genesis 38, Judah, one of the twelve sons of Jacob, fathers twin sons with his daughter-in-law Tamar, under scandalous circumstances. Tamar, after being denied justice by Judah following the deaths of his sons Er and Onan, disguises herself as a prostitute to provoke Judah to fulfill his familial duty of providing offspring.

When Tamar becomes pregnant, Judah unknowingly becomes the father. Months later, she is brought forward to be punished for her apparent immorality, but she reveals Judah’s identity as the father. Judah acknowledges his wrongdoing, saying, “She is more righteous than I” (Genesis 38:26).

During the birth, one baby extends a hand, and the midwife ties a scarlet thread around it, identifying him as the firstborn. But then his brother, Perez (“breach”), pushes past and is born first. The second son, with the scarlet thread, is Zarah.

This reversal sets a pattern in Scripture where the expected firstborn blessing is disrupted by divine choice, as seen with Isaac over Ishmael, Jacob over Esau, Joseph over Reuben, and David over his brothers.

Meaning for Today’s Christians

Zarah’s story reminds Christians that God‘s ways are not bound by human expectations or traditions. While Zarah was marked as the firstborn by human hands, God chose Perez, through whom the Messiah would come (Matthew 1:3). This underscores the biblical theme that God often exalts the lowly and chooses the unexpected.

Zarah also highlights that our position or status is not what determines our spiritual legacy. Though Zarah was not in the messianic line, his descendants became a notable clan within Judah, and his name is preserved in Scripture, revealing that God does not overlook anyone.

The scarlet thread tied to Zarah’s hand is also seen by many Christians as a symbol of redemption. The color scarlet often represents atonement and sacrifice (Isaiah 1:18; Hebrews 9:22). Although Zarah did not become the chosen line, his brief role in this narrative echoes the message of God‘s redemptive thread running through all of history.

How Zarah’s Story Points to Jesus and the Gospel

While Zarah was not the ancestor of Christ, his brother Perez was. However, their shared story sets the stage for understanding the nature of divine election and grace over legalism. Just as Perez’s unexpected emergence signaled God‘s sovereign choice, so too does Jesus’ coming shatter human expectations of the Messiah.

Furthermore, Tamar, their mother, is one of the few women mentioned in the genealogy of Jesus (Matthew 1:3). Her inclusion, and that of her twin sons, reveals that Jesus came through broken, sinful, and complex family lines to redeem broken, sinful, and complex people.

Zarah’s scarlet thread has been seen by many early Christian interpreters as a foreshadowing of Christ‘s blood—the true mark of salvation—not tied to lineage, birth order, or human merit, but to grace.
