1Jacob called to his sons, and said: “Gather yourselves together, that I may tell you that which will happen to you in the days to come.
2Assemble yourselves, and hear, you sons of Jacob.
Listen to Israel, your father.
3“Reuben, you are my firstborn, my might, and the beginning of my strength,
excelling in dignity, and excelling in power.
4Boiling over like water, you shall not excel,
because you went up to your father’s bed,
then defiled it. He went up to my couch.
5“Simeon and Levi are brothers.
Their swords are weapons of violence.
6My soul, don’t come into their council.
My glory, don’t be united to their assembly;
for in their anger they killed men.
In their self-will they hamstrung cattle.
7Cursed be their anger, for it was fierce;
and their wrath, for it was cruel.
I will divide them in Jacob,
and scatter them in Israel.
8“Judah, your brothers will praise you.
Your hand will be on the neck of your enemies.
Your father’s sons will bow down before you.
9Judah is a lion’s cub.
From the prey, my son, you have gone up.
He stooped down, he crouched as a lion,
as a lioness.
Who will rouse him up?
10The scepter will not depart from Judah,
nor the ruler’s staff from between his feet,
until he comes to whom it belongs.
The obedience of the peoples will be to him.
11Binding his foal to the vine,
his donkey’s colt to the choice vine,
he has washed his garments in wine,
his robes in the blood of grapes.
12His eyes will be red with wine,
his teeth white with milk.
13“Zebulun will dwell at the haven of the sea.
He will be for a haven of ships.
His border will be on Sidon.
14“Issachar is a strong donkey,
lying down between the saddlebags.
15He saw a resting place, that it was good,
the land, that it was pleasant.
He bows his shoulder to the burden,
and becomes a servant doing forced labor.
16“Dan will judge his people,
as one of the tribes of Israel.
17Dan will be a serpent on the trail,
an adder in the path,
that bites the horse’s heels,
so that his rider falls backward.
18I have waited for your salvation, Yahweh.
19“A troop will press on Gad,
but he will press on their heel.
20“Asher’s food will be rich.
He will produce royal dainties.
21“Naphtali is a doe set free,
who bears beautiful fawns.
22“Joseph is a fruitful vine,
a fruitful vine by a spring.
His branches run over the wall.
23The archers have severely grieved him,
shot at him, and persecuted him:
24But his bow remained strong.
The arms of his hands were made strong,
by the hands of the Mighty One of Jacob,
(from there is the shepherd, the stone of Israel),
25even by the God of your father, who will help you,
by the Almighty, who will bless you,
with blessings of heaven above,
blessings of the deep that lies below,
blessings of the breasts, and of the womb.
26The blessings of your father have prevailed above the blessings of my ancestors,
above the boundaries of the ancient hills.
They will be on the head of Joseph,
on the crown of the head of him who is separated from his brothers.
27“Benjamin is a ravenous wolf.
In the morning he will devour the prey.
At evening he will divide the plunder.”
28All these are the twelve tribes of Israel, and this is what their father spoke to them, and blessed them. He blessed everyone according to his own blessing. 29He instructed them, and said to them, “I am to be gathered to my people. Bury me with my fathers in the cave that is in the field of Ephron the Hittite, 30in the cave that is in the field of Machpelah, which is before Mamre, in the land of Canaan, which Abraham bought with the field from Ephron the Hittite as a burial place. 31There they buried Abraham and Sarah, his wife. There they buried Isaac and Rebekah, his wife, and there I buried Leah: 32the field and the cave that is therein, which was purchased from the children of Heth.” 33When Jacob finished charging his sons, he gathered up his feet into the bed, breathed his last breath, and was gathered to his people.
Isaac was the son of promise to Abraham and Sarah, and the half-brother of Ishmael (who became the father of the Arab people) and the father of Esau (from whom came the Edomites) and Jacob. Isaac was born of a mother beyond childbearing age by a miracle of Yahweh, and was a focus of the testing of Abraham and Sarah, his parents.
The name Isaac means "to laugh, or he laughs," which is based on the response of Sarah to Yahweh's statement to Abraham that she was to bear a son. Sarah was hiding out of sight when this announcement was made by the Angel of Yahweh, and upon hearing this statement, she laughed, which she denied later before the angel. Such an idea was considered impossible but happened as promised by the heavenly visitor. Later, Abraham's faith was tested when God commanded him to sacrifice his only son, Isaac. He followed through with this command of God but received him back alive, since Yahweh kept him from doing so, declaring that now He knew by experience (see the meaning of Hebrew yada') that Abram did not withhold his son.
Later in Isaac's life, he married Rebekah, who bore him Jacob (biography) and Esau (his favorite), and was tricked by Jacob and Rebekah into giving his younger son Jacob his blessing.
Isaac was the only son of Abraham and Sarah, a half-brother of Ishmael and father of Esau and Jacob. Isaac was born when both of his parents were very old, the circumstances surrounding his birth being a test of their faith. The meaning of Isaac's name (“he laughs”) is explained by the fact that Abraham laughed when he was told a son would be born to him at the age of a hundred. Abraham's faith was further tested when he was told to sacrifice Isaac but was stopped at the last moment from carrying out this instruction.
