As an aside, when I first looked at this question about mingled people I thought of the church of Pergamos often referred to as the married church. This was the marriage of the early apostolic church and pagan Rome.
Emperor Constantine had a vision during the campaign against Maxentius in which the Christian sign appeared in the sky with the legend “In this sign, conquer.” As a result of his victory, Constantine converted to Christianity. There is some question as to his total commitment to Christianity or whether his was just a political move. In any event, the church of Thyatira resulted with its many pagan icons and practices.
So here the mingling the apostolic church with the pagan church resulted in hundreds of years of false doctrine and relegation of the laity to the authority of the clergy.
Then there is the interesting concept of fallen angels and their off-spring.
Ezekiel 30:5, “Ethiopia, and Libya, and Lydia, and all the mingled people, and Chub, and the men of the land that is in league, shall fall with them by the sword.”
Does this harken back to Geneses 6:2, “That the sons of God saw the daughters of men that they were fair; and they took them wives of all which they chose.”
Continuing in Geneses 6:4, “There were giants in the earth in those days; and also after that, when the sons of God came in unto the daughters of men, and they bare children to them, the same became mighty men which were of old, men of renown.”
Giants, Strong’s H5303, a bully or tyrant: - giant
Brown Driver Briggs Hebrew Definition: 1) giants, the Nephilim
Daniel 2:43, “And whereas thou sawest iron mixed with miry clay, they shall mingle themselves with the seed of men: but they shall not cleave one to another, even as iron is not mixed with clay.”
Strong’s H6154 – mingled, a mixture, (or mongrel race): - Arabia, mingled people, mixed.
Man has long tried to explain these Nephilim/ hybrids as the off-springs of the gods of old seducing the women of earth. The Greeks and Romans had very similar myths of beings who were half men and half god. What I once discounted as interesting fiction now resonate as fallen angels impregnating earth women.
References are made to the Rephaites in Genesis 14 and in Numbers 13:33, “We saw the Nephilim there (the descendants of Anak come from the Nephilim). We seemed like grasshoppers in our own eyes, and we looked the same to them.” There are additional references in the Old Testament, enough to prove that they were still around after the flood.
The human species is beings coming so evil that perhaps Satan doesn’t need his minions, the fallen angels, to corrupt humans. There are hints of research in the area of Chimeras perhaps driven by the dream of the perfect soldier. As humans flirt with Transhumanism, the singularity point and introducing animal DNA into humans we are indeed in the days prophesied “As it was and the days of Noah.” Perhaps the greatest warning against research into combining human and animal DNA is the concern that Chimeras are unredeemable.
I believe that all kinds of monsters exist today, however, far more concerning are the monsters being created in the minds of men. In our continuing arrogance surely we will “Inherit the wind.”
