The Nephilim were on the earth in those days *—and also afterward—*when the sons of God went to the daughters of humans and had children by them. They were the heroes of old, men of renown.
Genesis 6:4 NIV
In still another battle, which took place at Gath, there was a huge man with six fingers on each hand and six toes on each foot—twenty-four in all. He also was descended from Rapha. When he taunted Israel, Jonathan son of Shimeah, David’s brother, killed him. These four were descendants of Rapha in Gath, and they fell at the hands of David and his men.
2 Samuel 21:20-22 NIV
They never left.
