On his return from Egypt Abraham's relations to his own family were disturbed by annoying circumstances. Strife developed between the herdmen of his cattle and the herdmen of Lot's cattle. Abraham furnished his herds with muzzles, but Lot made no such provision, and when the shepherds that pastured Abraham's flocks took Lot's shepherds to task on account of the omission, the latter replied: "It is known of a surety that God said unto Abraham, 'To thy seed will I give the land.'

But Abraham is a sterile mule. Never will he have children. On the morrow he will die, and Lot will be his heir. Thus the flocks of Lot are but consuming what belongs to them or their master."

But God spoke: "Verily, I said unto Abraham I would give the land unto his seed, but only after the seven nations shall have been destroyed from out of the land. To-day the Canaanites are therein, and the Perizzites. They still have the right of habitation."
