Marty let's take a look at Jude which is the verification of the angels of Gen ch6
v5 - But I want to remind you, though you once knew this, that the Lord, having saved the people out of the land of Egypt, afterward destroyed those who did not believe.
v5 is Key to the understanding and is simple, one sentence, truth of what God did and to whom.
a.) saved people (all who obeyed the Passover)
b.) Passover - they came out of Egypt and slavery
c.) afterward - after they left Egypt, crossed the Red Sea and came to wait at the base of the Mountain where the Moses went up to meet the LORD.
d.) afterward - some did not believe and they fell back into sexual immorality and God destroyed them = Exodus ch32
This is the Picture we are to SEE of God's Judgment upon the people who came out of Egypt and corrupted themselves with sexual immorality and thus were destroyed by God's anger.
v6 begins with "And" connects v6 to v5
v6 And the angels who did not keep their proper domain, but left their own abode, He has reserved in everlasting chains under darkness for the judgment of the great day;
Angels had a domain ordered by God which they could not leave, just as the people who came out of Egypt.
What did these angels do when they left their "proper domain"?
Answer = v7
v7 as Sodom and Gomorrah, and the cities around them in a similar manner to these, having given themselves over to sexual immorality and gone after strange flesh, are set forth as an example, suffering the vengeance of eternal fire.
The angels who left there domain against the will of God "came into the daughters of men" = "strange flesh"
just as Sodom and Gomorrah violated God's Ordination of Male to Female marriage and committed homosexuality, beastiality, rapes, orgies and more.
ALL three Groups committed sexual immorality of such degree that God Judged them as an example for us to FEAR.
1st Group - People who came out of Egypt committed sexual immorality = left the domain of purity in the Lord
2nd Group - Angels who left their proper domain and came into the daughters of men = left their Ordered Domain from the Lord
3rd Group - Sodom and Gomorrah = committed all kinds of sexual perversion = left the domain of purity before God
These 3 Groups are combined into one uniform message of WARNING in one uninterupted passage of Truth.
