Genesis 38 shifts focus to Judah and his family, highlighting immorality and broken promises. Judah's two wicked sons die, and Tamar, the widow of Judah's eldest son, seeks justice through unconventional means. She disguises herself as a prostitute and tricks Judah into fathering twin sons, Perez and Zerah. The chapter reveals themes of sin, hypocrisy, and God’s grace, showing that even flawed individuals are woven into His redemptive plan. Perez becomes part of the lineage of Jesus, demonstrating the surprising ways God works through human frailty.
