23 The sons by Leʹah were Jacob’s firstborn Reuʹben,+ then Simʹe·on, Leʹvi, Judah, Isʹsa·char, and Zebʹu·lun.

5 These are the sons of Reuʹben,+ Israel’s firstborn. He was the firstborn, but because he defiled* the bed of his father,+ his right as firstborn was given to the sons of Joseph+ the son of Israel, so he was not enrolled genealogically for the right of the firstborn.
