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

3 “Reuʹben, you are my firstborn,+ my vigor and the beginning of my generative power,+ the excellence of dignity and the excellence of strength.

5 And the sons of Reuʹben+ the firstborn of Israel—for he was the firstborn;+ but for his profaning the lounge of his father+ his right as firstborn was given to the sons of Joseph+ the son of Israel, so that he was not to be enrolled genealogically for the right of the firstborn.
