The books that are considered to be "cannonical" differentiate. This is why the Ethiopian cannon includes more writings than Biblio. Europe did not always have the books together as one "authoritative" book. They started off with a few separated writings because that's how the scrolls were kept. The 1611 King James Biblio even had more books than it has now and mentions other writings they don't include. The writings could even have been copied more than some considered "cannonical". There are explicit prophecies in of Jesus in Enoch, The Testament of 12 Patriarchs, Eden aka The Books of Adam and Eve. I've heard that Enoch may have been one of the most quoted books by Jesus.
Jasher 56:9 Only teach thy sons the bow and all the weapons of war, in order that they may fight the battles of their brother who will rule over his enemies.
2 Samuel 1:18 (Also he bade them teach the children of Judah the use of the bow: behold, it is written in the book of Jasher.)
Jasher 89:8 The sun and moon stood still in heaven, and thou didst stand in thy wrath against our oppressors and didst command thy judgments over them.
Joshua 10:13 And the sun stood still, and the moon stayed, until the people had avenged themselves upon their enemies. Is not this written in the book of Jasher? So the sun stood still in the midst of heaven, and hasted not to go down about a whole day.
Jasher 2:4 And the sons of men went and they
served other gods, and they forgot the LORD who had created them in the earth
Jasher 2:6 And the LORD caused the waters of the river Gihon to overwhelm them, and he destroyed them, and he destroyed the third part of the earth, the sons of men did not turn from their evil ways, and their hands were yet extended to do evil in the sight of the LORD.
Jasher 2:11-12 And
Cainan became wise and had knowledge and skill in all wisdom, and he
led the sons of men to wisdom and knowledge; And Cainan knew by his wisdom that God would destroy the sons of men for having sinned upon earth, and that the LORD would in the latter days bring upon them the waters of the flood.
Jasher 2:16-17 And these are the names of the children of
Cainan; the name of the first born Mahlallel, the second Enan, and the third Mered, and their sisters were
Adah and Zillah. And
Lamech, the son of Methusael, became related to Cainan by marriage, and he took his two daughters for his wives
Jasher 9:7 And the king and all his servants, and
Terah with all his household were then the first of those that
served gods of wood and stone.
Joshua 24:2 And Joshua said unto all the people, Thus saith the LORD God of Israel, Your fathers dwelt on the other side of the flood in old time, even
Terah, the father of Abraham, and the father of Nachor: and they
served other gods.
Genesis 4:13-14 And Cain said unto the LORD, My punishment is greater than I can bear. Behold, thou hast driven me out this day from the face of the earth; and from thy face shall I be hid; and I shall be a fugitive and a wanderer in the earth; and it shall come to pass, that someone that findeth me shall slay me.
Jasher 2:26-31 And
Lamech was old , and had weakened eyesight, and Tubal Cain, his son, was leading him and one day Lamech went into the field and Tubal Cain his son was with him, and whilst they were walking in the field, Cain the son of Adam advanced towards them; for Lamech was very old and could not see much, and Tubal Cain his son was very young. And Tubal Cain told his father to draw his bow, and with the arrows he smote Cain, who was yet far off, and he slew him, for he appeared to them to be an animal. And the LORD requited Cain's evil according to his wickedness, which he had done to his brother Abel, according to the word of the LORD which he had spoken. And Lamech was very much grieved at having done this, and in clapping his hands together he struck his son and caused his death. And the wives of Lamech heard what Lamech had done, and they sought to kill him. And they separated from him, and would not hearken to him.
Jasher 2:35-36 And he said, Hear my voice, attend to my words, for now you have imagined and said that I slew a man with my wounds, and a child with my stripes for their having done no violence, but surely know that I am old and that my eyes are heavy through age, and I did this thing unknowingly. And they listened to him, and they returned to him with the advice of their father Adam.
Eden 13:2-3 and Lamech said to them, "As for me, I cannot feed those cattle alone, lest one rob me of some of them, or kill me for the sake of them." For among the children of Cain, there was much robbery, murder, and sin. Then Lamech pitied him, and he said, "Truly, he when alone, might be overpowered by the men of this place."
Eden 13:5-13 Meanwhile Cain, ever since God had cast him off, and had cursed him with trembling and terror, could neither settle nor find rest in any one place; but wandered from place to place. In his wanderings he came to Lamech's wives, and asked them about him. They said to him, "He is in the field with the cattle." Then Cain went to look for him; and as he came into the field, the young shepherd heard the noise he made, and the cattle herding together from before him. Then said he to Lamech, "O my lord, is that a wild beast or a robber?" And Lamech said to him, "Make me understand which way he looks, when he comes up." Then Lamech bent his bow, placed an arrow on it, and fitted a stone in the sling, and when Cain came out from the open country, the shepherd said to Lamech, "Shoot, behold, he is coming." Then Lamech shot at Cain with his arrow and hit him in his side. And Lamech struck him with a stone from his sling, that fell upon his face, and knocked out both his eyes; then Cain fell at once and died. Then Lamech and the young shepherd came up to him, and found him lying on the ground. And the young shepherd said to him, "It is Cain our grandfather, whom thou hast killed, O my lord!" Then was Lamech sorry for it, and from the bitterness of his regret, he clapped his hands together, and struck with his flat palm the head of the youth, who fell as if dead; but Lamech thought it was a feint; so he took up a stone and smote him, and smashed his head until he died.
Jasher 5:19-21 Lamech the father of Noah, died. All the days of Lamech were 777 years. And all the
sons of men who knew the LORD, died in that year before the LORD brought evil (the flood) upon them; for
the LORD willed them to die, so as not to behold the evil that God would bring upon their brothers and relatives, as he had so declared to do.
