The sons of God and the daughters of men
“As you saw iron mixed with ceramic clay, they will mingle (intermarry) with the seed of men; but they will not adhere to one another, just as iron does not mix with clay.” Dan 2:43
I think the key to Genesis 6 is that this pattern is repeated many times in the Bible. It was the sin of INTERMARRIAGE, of compromise between the priesthood and unbelieving women. Adultery and idolatry have a close connection.
There is godly intermarriage, such as Joseph’s and Solomon’s Egyptian wives, or like Ruth and the first century Gentiles, who married INTO the Covenant on God’s terms. And then there is ungodly intermarriage, where Midianite women or Solomon’s wives led the sons of God astray.
These sons of God in Genesis 6 are the sons of Seth. Blessed by God, their offspring were mighty men, warriors. It was always the intention that Eve’s offspring would be an army, but a godly one. But this ungodly army filled the world with violence and were wiped out in a flood. This pattern is repeated with Israel.
When the sons of Aaron ‘intermarried’ with false religion, the waters from below flooded up over the altar (the Land of Israel) – the Gentile armies of Babylon and Rome (Dan. 9:26). And water from above poured down (from the Laver – the crystal sea) to ‘baptize’ those who remained faithful.
The final compromise between Israel and the ‘daughters of men’ was the intermarriage (the literal translation of Dan 2:43) between the RED Edomite clay of the Herods and the ‘Philistine’ IRON of Rome. Esau had married foreign wives again, Balaam (the false prophet) tried to deceive the elect, and the Tabernacle’s Jew-Gentile feet became a counterfeit of Paul’s Jew-Gentile church. The end came with a flood, and God ’submerged’ the old creation as He did in the days of Noah (Matt 24:37). The ’sons of God’ priesthood of the Old Covenant was washed from the Land forever, but the new priesthood ascended upon the crystal sea, like Noah, in the ark of Christ.
Christ had said that the Temple would be destroyed, but Herod continued to build and glorify it. But “the rain descended, the floods came, and the winds blew and beat on that house; and it fell. And great was its fall.” Just as it was in the days of Noah.
