1 Chronicles 5:1-3

Living Bible

5 The oldest son of Israel was Reuben, but since he dishonored his father by sleeping with one of his father’s wives, his birthright was given to his half brother, Joseph. So the official genealogy doesn’t name Reuben as the oldest son.

² Although Joseph received the birthright, yet Judah was a powerful and influential tribe in Israel, and from Judah came a prince.

³ The sons of Reuben, Israel’s son, were: Hanoch, Pallu, Hezron, Carmi.
