Since I have access to this stuff, and some of you may not. And some may be interested. here is some more quotes/info:
Book of Jasher - Chapter 4
4. Apostasy to Noah’s Birth
987 AM – Enoch ascends
987 AM – Methuselah King
1 And all the days that Enoch lived upon earth, were three hundred and sixtyfive
years. 2 And when Enoch had ascended into heaven, all the kings of the
earth rose and took Methuselah his son and anointed him, and they caused him
to reign over them in the place of his father. 3 And Methuselah acted uprightly
in the sight of God, as his father Enoch had taught him, and he likewise during
the whole of his life taught the sons of men wisdom, knowledge and the fear of
God, and he did not turn from the good way either to the right or to the left. 4
But in the latter days of Methuselah, the sons of men turned from the Lord, they
corrupted the earth, they robbed and plundered each other, and they rebelled
against God and they transgressed, and they corrupted their ways, and would
not hearken to the voice of Methuselah, but rebelled against him. 5 And the
Lord was exceedingly wroth against them, and the Lord continued to destroy
the seed in those days, so that there was neither sowing nor reaping in the
earth. 6 For when they sowed the ground in order that they might obtain food
for their support, behold, thorns and thistles were produced which they did not
sow. 7 And still the sons of men did not turn from their evil ways, and their
hands were still extended to do evil in the sight of God, and they provoked the
Lord with their evil ways, and the Lord was very wroth, and repented that he
had made man. 8 And he thought to destroy and annihilate them and he did so.
1042 AM – Seth died
9 In those days when Lamech the son of Methuselah was one hundred and sixty
[168] years old, Seth the son of Adam died. 10 And all the days that Seth
lived, were nine hundred and twelve years, and he died. 11 And Lamech was
one hundred and eighty years old when he took Ashmua, the daughter of
Elishaa the son of Enoch his uncle, and she conceived. 12 And at that time the
sons of men sowed the ground, and a little food was produced, yet the sons of
men did not turn from their evil ways, and they trespassed and rebelled against
God.
1056 AM – Noah born
13 And the wife of Lamech conceived and bare him a son at that time, at the
revolution [RHS] of the year. 14 And Methuselah called his name Noah,
saying, The earth was in his days at rest and free from corruption, and Lamech
his father called his name Menachem, saying, This one shall comfort us in our
works and miserable toil in the earth, which God had cursed. 15 And the child
grew up and was weaned, and he went in the ways of his father Methuselah,
perfect and upright with God. 16 And all the sons of men departed from the
ways of the Lord in those days as they multiplied upon the face of the earth
with sons and daughters, and they taught one another their evil practices and
they continued sinning against the Lord. 17 And every man made unto himself a
god, and they robbed and plundered every man his neighbor as well as his
relative, and they corrupted the earth, and the earth was filled with violence.
18 And their judges and rulers went to the daughters of men and took their
wives by force from their husbands according to their choice, and the sons of
men in those days took from the cattle of the earth, the beasts of the field and
the fowls of the air, and taught the mixture of animals of one species with the
other, in order therewith to provoke the Lord; and God saw the whole earth
and it was corrupt, for all flesh had corrupted its ways upon earth, all men and
all animals. 19 And the Lord said, I will blot out man that I created from the
face of the earth, yea from man to the birds of the air, together with cattle and
beasts that are in the field for I repent that I made them. 20 And all men who
walked in the ways of the Lord, died in those days, before the Lord brought the
evil upon man which he had declared, for this was from the Lord, that they
should not see the evil which the Lord spoke of concerning the sons of men. 21
And Noah found grace in the sight of the Lord, and the Lord chose him and his
children to raise up seed from them upon the face of the whole earth.
I can't figure out how trustworthy the Book of Jasher is. Hard to tell if some or all of the details are trustworthy. Ken Johnson Th.D has studied these matters a lot and writes lots of books on these topics.
But the Book of Jasher/Jashar IS mentioned by name in the Bible:
“So the sun stood still, and the moon stopped, Until the nation avenged themselves of their enemies. Is it not written in the book of Jashar? And the sun stopped in the middle of the sky and did not hasten to go down for about a whole day.” (Joshua 10:13, NASB95)
“Then David chanted with this lament over Saul and Jonathan his son, and he told them to teach the sons of Judah the bow; behold, it is written in the book of Jashar.” (2 Samuel 1:17–18, NASB95)
