"the gifts that Avraham gave to those sons were actually 'unclean names' (evil powers)" ~ Genesis 25:6 Rashi
"Avraham knew that these powers already existed in the East. If his sons would have gone there without knowing these powers they would have become subservient to those with the powers. But since they too could wield such things they were able to push off that influence." ~ Reb Gutman
