Blessings

Abraham speaks with Rebekah about Jacob and Esau
Jubilees 19:15-25
And Abraham loved Jacob, but Isaac loved Esau. And Abraham saw the deeds of Esau, and he knew that in Jacob should his name and seed be called; and he called Rebecca and gave commandment regarding Jacob, for he knew that she too loved Jacob much more than Esau. And he said unto her, “My daughter, watch over my son Jacob, for he will be in my stead on the earth, and for a blessing amid the children of men, and for the glory of the whole seed of Shem. For I know that the Lord will choose him to be a people for possession to Himself, above all peoples that are upon the face of the earth. And behold, Isaac my son loves Esau more than Jacob, but I see that you truly love Jacob. Add still further to your kindness to him, and let your eyes be upon him in love; for he will be a blessing to us on the earth from henceforth to all generations of the earth. Let your hands be strong and let your heart rejoice in your son Jacob; for I have loved him far beyond all my sons. He will be blessed forever, and his seed will fill the whole earth. If a man can number the sand of the earth, his seed also will be numbered. And all the blessings wherewith the Lord has blessed me and my seed will belong to Jacob and his seed always. And in his seed will my name be blessed, and the name of my fathers, Shem, and Noah, and Enoch, and Mahalalel, and Enos, and Seth, and Adam. And these will serve to lay the foundations of the heaven, and to strengthen the earth, and to renew all the luminaries which are in the firmament.”

Abraham blesses Jacob
Jubilees 19:26-30
And he called Jacob before the eyes of Rebecca his mother, and kissed him, and blessed him, and said: “Jacob, my beloved son, whom my soul loves, may God bless you from above the firmament, and may He give you all the blessings wherewith He blessed Adam, and Enoch, and Noah, and Shem; and all the things of which He told me, and all the things which He promised to give me, may he cause to cleave to you and to your seed forever, according to the days of heaven above the earth. And the Spirits of Mastêmâ will not rule over you or over your seed to turn you from the Lord, who is your God from henceforth forever. And may the Lord God be a father to you and you the first-born son, and to the people always. Go in peace, my son.”

And they both went forth together from Abraham.

Isaac loves Esau more and Rebekah loves Jacob more
Genesis 25:28, Jubilees 19:31
And Rebecca loved Jacob, with all her heart and with all her soul, very much more than Esau; but Isaac loved Esau much more than Jacob because he did eat of his venison.

Abraham instructs Isaac
Jasher 26:22-28, Jubilees 21:1-26
And in the 6th year of the 7th week of this jubilee, Abraham called Isaac his son and commanded him: saying, “I am become old, and know not the day of my death, and am full of my days.”

And he commanded him saying, “Do you not know and understand the Lord is God in heaven and earth, and there is no other beside him? And it was he who took me from my father’s house, and from my birth place, and gave me all the delights upon the earth; who delivered me from the counsel of the wicked, for in him did I trust. And he brought me to this place, and he delivered me from Ur Casdim; and he said to me, ‘To your seed will I give all these lands, and they will inherit them when they keep my commandments, my statutes and my judgments that I have commanded you, and which I shall command them.’ Now, therefore, my son, listen to my voice, and keep the commandments of the Lord your God, which I commanded you, do not turn from the right way either to the right or to the left, so that it may be well with you and your children after you forever. And remember the wonderful works of the Lord, and his kindness that he has shown toward us, in having delivered us from the hands of our enemies, and the Lord our God caused them to fall into our hands; and now, therefore, keep all that I have commanded you, and turn not away from the commandments of your God, and serve none beside him, so that it may be well with you and your seed after you. And teach your children and your seed the instructions of the Lord and his commandments, and teach them the upright way in which they should go, in order that it may be well with them forever.”

“And behold, I am 175 years old, and throughout all the days of my life I have remembered the Lord and sought with all my heart to do His will, and to walk uprightly in all His ways. My soul has hated idols, and I have despised those that served them, and I have given my heart and spirit that I might observe to do the will of Him who created me. For He is the living God, and He is holy and faithful, and He is righteous beyond all, and there is with Him no accepting of men’s persons and no accepting of gifts; for God is righteous, and executes judgment on all those who transgress His commandments and despise His covenant. And you, my son, observe His commandments and His ordinances and His judgments, and walk not after the abominations and after the graven images and after the molten images. And eat no blood at all of animals or cattle, or of any bird which flies in the heaven. And if you do slay a victim as an acceptable peace offering, slay it, and pour out its blood upon the altar, and all the fat of the offering offer on the altar with fine flour and the meat offering mingled with oil, with its drink offering, offer them all together on the altar of burnt offering; it is a sweet savor before the Lord. And you will offer the fat of the sacrifice of thank offerings on the fire which is upon the altar, and the fat which is on the belly, and all the fat on the inwards and the 2 kidneys, and all the fat that is upon them, and upon the loins and liver you will remove, together with the kidneys. And offer all these for a sweet savor acceptable before the Lord, with its meat-offering and with its drink-offering, for a sweet savor, the bread of the offering to the Lord. And eat its meat on that day and on the 2nd day, and let not the sun on the 2nd day go down upon it until it is eaten, and let nothing be left over for the 3rd day; for it is not acceptable for it is not approved and let it no longer be eaten, and all who eat thereof will bring sin upon themselves; for thus I have found it written in the books of my forefathers, and in the words of Enoch, and in the words of Noah. And on all your oblations you will strew salt, and let not the salt of the covenant be lacking in all your oblations before the Lord. And as regards the wood of the sacrifices, beware unless you bring other wood for the altar in addition to these: cypress, bay, almond, fir, pine, cedar, savin, fig, olive, myrrh, laurel, or aspalathus. And of these kinds of wood laid upon the altar under the sacrifice, such as have been tested as to their appearance, and do not lay thereon any split or dark wood, but hard and clean, without fault, a sound and new growth; and do not lay thereon old wood, for its fragrance is gone for there is no longer fragrance in it as before. Besides these kinds of wood, there is none other that you will place on the altar, for the fragrance is dispersed, and the smell of its fragrance goes not up to heaven. Observe this commandment and do it, my son, that you may be upright in all your deeds. And at all times be clean in your body, and wash yourself with water before you approach to offer on the altar, and wash your hands and your feet before you draw near to the altar; and when you are done sacrificing, wash again your hands and your feet. And let no blood appear upon you nor upon your clothes; be on your guard, my son, against blood, be on your guard exceedingly; cover it with dust. And do not eat any blood for it is the soul; eat no blood whatever. And take no gifts for the blood of man, unless it is shed with impunity, without judgment; for it is the blood that is shed that causes the earth to sin, and the earth cannot be cleansed from the blood of man save by the blood of him who shed it. And take no present or gift for the blood of man: blood for blood, that you may be accepted before the Lord, the Most High God; for He is the defense of the good: and that you may be preserved from all evil, and that He may save you from every kind of death. I see, my son, that all the works of the children of men are sin and wickedness, and all their deeds are uncleanness and an abomination and a pollution, and there is no righteousness with them. Beware, unless you should walk in their ways and tread in their paths, and sin a sin to death before the Most High God. Else He will hide His face from you and give you back into the hands of your transgression, and root you out of the land, and your seed likewise from under heaven, and your name and your seed will perish from the whole earth. Turn away from all their deeds and all their uncleanness, and observe the ordinance of the Most High God, do His will, and be upright in all things. And He will bless you in all your deeds, and will raise from you a plant of righteousness through all the earth, throughout all generations of the earth, and my name and your name will not be forgotten under heaven forever. Go, my son in peace. May the Most High God, my God, and your God, strengthen you to do His will, and may He bless all your seed and the residue of your seed for the generations forever, with all righteous blessings, that you may be a blessing on all the earth.”

And Isaac answered his father and said to him, “That which my Lord has commanded that will I do, and I will not depart from the commands of the Lord my God, I will keep all that he commanded me;” and Abraham blessed his son Isaac, and also his children; and Abraham taught Jacob the instruction of the Lord and his ways. And he went out from him rejoicing.

Isaac and Ishmael celebrate the feast of weeks with Abraham
Jubilees 22:1-5
And it came to pass in the 1st week in the 44th jubilee, in the 2nd year, that is, the year in which Abraham died, that Isaac and Ishmael came from the Well of the Oath to celebrate the feast of weeks -that is, the feast of the first fruits of the harvest- to Abraham, their father, and Abraham rejoiced because his 2 sons had come. For Isaac had many possessions in Beersheba, and Isaac was not wanting to go and see his possessions and to return to his father.

And in those days Ishmael came to see his father, and they both came together, and Isaac offered a sacrifice for a burnt offering, and presented it on the altar of his father which he had made in Hebron. And he offered a thank offering and made a feast of joy before Ishmael, his brother: and Rebecca made new cakes from the new grain, and gave them to Jacob, her son, to take them to Abraham, his father, from the first fruits of the land, that he might eat and bless the Creator of all things before he died. And Isaac, too, sent by the hand of Jacob to Abraham a best thank offering, that he might eat and drink.
