Traditions of Men have removed these Holy Spirit inspired texts. I implore anyone who is hesitant of these to research the findings at the Qumran Caves, aka Dead Sea Scrolls. Books like this, 2 Esdras and Enoch and Jasher and Jubilees and many others were found preserved alongside canonical books. They are not contradicting, but yet complimentary to our 66 book canon. Be a Berean and test these things with the spirit!

The Matthew 22 Saducee encounter
23 The same day came to him the Sadducees, which say that there is no resurrection, and asked him,
24 Saying, Master, Moses said, If a man die, having no children, his brother shall marry his wife, and raise up seed unto his brother.
25 Now there were with us seven brethren: and the first, when he had married a wife, deceased, and, having no issue, left his wife unto his brother:
26 Likewise the second also, and the third, unto the seventh.
27 And last of all the woman died also.
28 Therefore in the resurrection whose wife shall she be of the seven? for they all had her.
29 Jesus answered and said unto them, Ye do err, not knowing the scriptures, nor the power of God.
30 For in the resurrection they neither marry, nor are given in marriage, but are as the angels of God in heaven.
31 But as touching the resurrection of the dead, have ye not read that which was spoken unto you by God, saying,
32 I am the God of Abraham, and the God of Isaac, and the God of Jacob? God is not the God of the dead, but of the living.
Enoch Scripture Jesus quoted from:
15:6 “Indeed you, formerly you were spiritual, having eternal life; and immortal in all the generations of the world.”
15:7 “That is why formerly I did not make wives for you, for the dwelling of the spiritual beings of heaven is heaven.’”
Enoch 15:6-7
