60 ページ - For the land, whither thou goest in to possess it, is not as the land of Egypt, from whence ye came out, where thou sowedst thy seed, and wateredst it with thy foot, as a garden of herbs : but the land, whither ye go to possess it, is a land of hills and valleys, and drinketh water of the rain of heaven...
