Very interesting paper; thanks for posting the link.
The invaders from Arabia occupied the south of Palestine and simultaneously moved toward Egypt. They conquered Egypt without meeting resistance.
The Amalekite conquerors came from Arabia, but apparently they had Hamitic blood in their veins. They were a nation of herdsmen and roamed with their large herds from field to field.
They mutilated the wounded and the prisoners, cut off limbs, and were unspeakably cruel in many other ways. They stole children and carried off women; they burned cities; they destroyed monuments and objects of art that had survived the catastrophe, and despoiled Egypt of her wealth. They were contemptuous of the religious feelings of the Egyptians.
The Amalekites built a city-fortress on the northeastern border of Egypt. Their chieftains were pharaohs and ruled from their fortress.
