When Jacob saw [his cousin] Rachel, the daughter of Laban, his mother’s brother, and Laban’s sheep, he came up and rolled the stone away from the mouth of the well and watered the flock of Laban, his uncle.

But Jacob said, “My son shall not go down [to Egypt] with you; for his brother is dead, and he alone is left [of Rachel’s children]. If any harm or accident should happen to him on the journey you are taking, then you will bring my gray hair down to Sheol (the place of the dead) in sorrow.”

And he looked up and saw his brother Benjamin, his mother’s [only other] son, and said, “Is this your youngest brother, of whom you spoke to me?” And Joseph said, “God be gracious to you and show you favor, my son.”

We said to my lord, ‘We have an old father and a young [brother, Benjamin, the] child of his old age. Now his brother [Joseph] is dead, and he alone is left of [the two sons born of] his mother, and his father loves him.’
