Biblical Flat Earth Awakening

"Jesus answered and said unto them, Ye do err, not knowing the scriptures, nor the power of God. For in the resurrection they neither marry, nor are given in marriage, but are as the angels of God in heaven."
Matthew 22:29-30

Jesus said: “Ye do err, not knowing the scriptures …”

What scriptures is Jesus referring to?

Nowhere in the canonical Scriptures does it say anything about marriage in the resurrection or angels are not supposed to marry.

It does however say so in another place:
The Book of 1 Enoch:

15.4 And you were spiritual, Holy, living an eternal life, but you became unclean upon the women, and begot children through the blood of flesh, and lusted after the blood of men, and produced flesh and blood, as they do, who die and are destroyed.
15.5 And for this reason I give men wives; so that they might sow seed in them, and so that children might be born by them, so that deeds might be done on the Earth.
15.6 But you, formerly, were spiritual, living an eternal, immortal life, for all the generations of the world.
15.7 For this reason I did not arrange wives for you; because the dwelling of the spiritual ones is in Heaven.
15.8 And now, the giants who were born from body and flesh will be called Evil Spirits on the Earth, and on the Earth will be their dwelling.

This is fascinating! Never knew it! Thanks for sharing, dear brother!

IMHO, Jesus is saying they err because they don't believe in the resurrection of the dead. He then told them that the problem they presented is not proof against it, but rather the answer is that there is no marriage.
