1 Chronicles 5:1

NOW [we come to] the sons of Reuben the firstborn of Israel. For [Reuben] was the eldest, but because he polluted his father's couch [with Bilhah his father's concubine] his birthright was given to the sons of Joseph [favorite] son of Israel; so the genealogy is not to be reckoned according to the birthright. [Gen. 35:22; 48:15-22; 49:3, 4.]
