And when Rachel saw that Leah had borne four sons to Jacob, Reuben and Simeon and Levi and Judah, she said unto him: "Go in unto Bilhah my handmaid, and she will conceive, and bear a son unto me."

(And she gave (him) Bilhah her handmaid to wife.) And he went in unto her, and she conceived, and bare him a son, and he called his name Dan, on the ninth of the sixth month, in the sixth year of the third week.

And Jacob went in again unto Bilhah a second time, and she conceived, and bare Jacob another son, and Rachel called his name Naphtali, on the fifth of the seventh month, in the second year of the fourth week.
