Abraham was a Sumerian / Chaldean priest from Ur. He 'went over' the Euphrates to Canaan. He then moved onto Egypt. Ultimately he returned to Canaan with a 'mixed horde' of people he had 'chosen' to be HIS people. It took 40 years, a few generations of cult brainwashing, from birth, to produce the genocidal cult mentality required to 'rip up pregnant women', and kill every man, woman, child, infant, and animal, that was living peacefully in the land he wanted for himself.
