1 Chronicles 5:1-2

New Catholic Bible

Chapter 5

Reuben. ¹ The sons of Reuben, the firstborn of Israel (for he was the firstborn, but when he defiled his father’s bed, his birthright was given to the sons of Joseph, the son of Israel. For this reason he could not be listed in the genealogy according to his birthright. ² Though Judah was the strongest of the brothers and a ruler came through him, the birthright belonged to Joseph.)
