Jacob loved Rachel, so he said, “I will serve you [as a hired workman] for seven years [in return] for [the privilege of marrying] Rachel your younger daughter.”

That made Jacob angry with Rachel, so he asked her, "Can I take God's place, who has not allowed you to conceive?"

And Bilhah Rachel's maid conceived again, and bare Jacob a second son.

And Laban went into Jacob's tent, and into Leah's tent, and into the two maidservants' tents; but he found them not. Then went he out of Leah's tent, and entered into Rachel's tent.

And Jacob set a pillar upon her grave: that is the pillar of Rachel's grave unto this day.

Rachel’s sons were
Joseph and Benjamin.

And the sons of Bilhah, Rachel's handmaid; Dan, and Naphtali:

Jacob's wife Rachel's sons were Joseph and Benjamin.

These were Rachel’s sons who were born to Jacob: 14 persons.

When thou art departed from me to day, then thou shalt find two men by Rachel's sepulchre in the border of Benjamin at Zelzah; and they will say unto thee, The asses which thou wentest to seek are found: and, lo, thy father hath left the care of the asses, and sorroweth for you, saying, What shall I do for my son?
