These were the sons of Reuben the firstborn of Israel. Though he was the firstborn, his birthright was given to the sons of Joseph son of Israel, because Reuben defiled his father’s bed. So he is not reckoned according to birthright. And though Judah prevailed over his brothers and a ruler came from him, the birthright belonged to Joseph.
Earlier text
Reuben, you are my firstborn, my might, and the beginning of my strength, excelling in honor, excelling in power. Uncontrolled as the waters, you will no longer excel, because you went up to your father's bed, onto my couch, and defiled it.
The Chronicler explicitly interprets Genesis 49:3-4 when explaining why Reuben's genealogy does not hold the firstborn position: "he defiled his father's bed" (1 Chr 5:1), referencing Reuben's sin with Bilhah. Jacob's blessing had declared Reuben "unstable as water" (pachaz kamayim) and stripped him of preeminence. The Chronicler adds the crucial note that "the birthright was given to the sons of Joseph" while "the ruler came from Judah" (ki Yehudah gavar be-echav uminnagid mimmennu), distinguishing the double-portion (Joseph) from the royal line (Judah). This interpretive comment is unique to Chronicles and directly exegetes the Genesis 49 oracle. The Chronicler's term for this forfeited status—בְּכֹרָה (bekorah, "birthright")—makes explicit what Jacob's oracle left implicit, confirming Reuben's loss as the enacted consequence of his sin rather than an arbitrary reassignment.
