And I will bless (do good for, benefit) those who bless you,
And I will curse [that is, subject to My wrath and judgment] the one who curses (despises, dishonors, has contempt for) you.
And in you all the families (nations) of the earth will be blessed.”

All these are the [beginnings of the] twelve tribes of Israel, and this is what their father said to them as he blessed them, blessing each one according to the blessing appropriate to him.

He also said,

“Blessed be the Lord,
The God of Shem;
And let Canaan be his servant.

And I will make you a great nation,
And I will bless you [abundantly],
And make your name great (exalted, distinguished);
And you shall be a blessing [a source of great good to others];

And Melchizedek blessed Abram and said,

“Blessed (joyful, favored) be Abram by God Most High,
Creator and Possessor of heaven and earth;

I will bless her, and indeed I will also give you a son by her. Yes, I will bless her, and she shall be a mother of nations; kings of peoples will come from her.”

since Abraham is destined to become a great and mighty nation, and all the nations of the earth will be blessed through him?

indeed I will greatly bless you, and I will greatly multiply your descendants like the stars of the heavens and like the sand on the seashore; and your seed shall possess the gate of their enemies [as conquerors].

Through your seed all the nations of the earth shall be blessed, because you have heard and obeyed My voice.”

I will make your descendants multiply as the stars of the heavens, and will give to your descendants all these lands; and by your descendants shall all the nations of the earth be blessed,

So he came and kissed him; and Isaac smelled his clothing and blessed him and said,

“The scent of my son [Esau]
Is like the aroma of a field which the Lord has blessed;

Then Isaac trembled violently, and he said, “Then who was the one [who was just here] who hunted game and brought it to me? I ate all of it before you came, and I blessed him. Yes, and he [in fact] shall be (shall remain) blessed.”

Esau replied, “Is he not rightly named Jacob (the supplanter)? For he has supplanted me these two times: he took away my birthright, and now he has taken away my blessing. Have you not reserved a blessing for me?”

Esau said to his father, “Have you only one blessing, my father? Bless me, even me also, O my father.” Then Esau [no longer able to restrain himself] raised his voice and wept [loudly].

So Esau hated Jacob because of the blessing with which his father blessed him; and Esau said in his heart, “The days of mourning for my father are very near; then I will kill my brother Jacob.”

Now Esau noticed that Isaac had blessed Jacob and sent him to Paddan-aram to take a wife for himself from there, and that as he blessed him he gave him a prohibition, saying, “You shall not take a wife from the daughters of Canaan,”

Your descendants shall be as [countless as] the dust of the earth, and you shall spread abroad to the west and the east and the north and the south; and all the families (nations) of the earth shall be blessed through you and your descendants.

It happened that from the time that he made Joseph overseer in his house and [put him in charge] over all that he owned, that the Lord blessed the Egyptian’s house because of Joseph; so the Lord’s blessing was on everything that Potiphar owned, in the house and in the field.

Then Jacob blessed them that day, saying,

“By you Israel will pronounce a blessing, saying,
‘May God make you like Ephraim and Manasseh.’”

And he put Ephraim before Manasseh.
