While the world was young, nations could be founded peaceably. There was plenty of unoccupied country, and when two neighbouring patriarchs found their flocks were becoming too numerous for the pasture, one said to the other: "Let there be no quarrel, I pray, between thee and me; the whole earth is between us, and the land is watered as the garden of Paradise. If thou wilt go to the east, I will go to the west; or if thou wilt go to the west, I will go to the east." So they parted in peace.(excerpt from book)
