Nephilim and relevance
One of the oddest bits of Genesis is this from chapter 6:
When people began to multiply on the face of the ground, and daughters were born to them, the sons of God saw that they were fair; and they took wives for themselves of all that they chose. Then the Lord said, ‘My spirit shall not abide in mortals for ever, for they are flesh; their days shall be one hundred and twenty years.’ The Nephilim were on the earth in those days—and also afterwards—when the sons of God went in to the daughters of humans, who bore children to them. These were the heroes that were of old, warriors of renown.
What on earth—or heaven for that matter—is this all about?
