And the LORD said to Abram, after Lot had separated from him, "Lift your eyes now and look from the place where you are; northward, southward, eastward, and westward. For all the land which you see I give to you and your descendants forever."
Genesis 13

Abram and Lot moved their tents and their flocks to many places, where they could find grass for their flocks and water to drink. At one time they went down to the land of Egypt, where they saw the great river Nile. Perhaps they saw also the Pyramids, and the Sphinx, and the wonderful temples in that land, for many of them were built before Abram lived.

Abram did not stay long in the land of Egypt. God did not wish him to live in a land where the people worshipped idols; so God sent Abram back again to the land of Canaan, to where Bethel stood later.

Now Lot, the son of Abram's younger brother who had died, was with Abram; and Lot, like Abram, had flocks of sheep and herds of cattle, and many tents for his people. Abram's shepherds and Lot's shepherds quarreled, because there was not grass enough in one place for both of them to feed their flocks; and besides these people, the Canaanites were also in the land, so that there was not room for them all.

When Abram heard of the quarrel between his men and the men under Lot, he said to Lot,
"Let there be no quarrel between you and me, nor between your men and my men; for you and I are like brothers to each other. The whole land is before us; let us go apart. You shall have the first choice, too. If you will take the land on the right hand, then I will take the land on the left; or if you choose the left hand, then I will take the right."

This was noble and generous in Abram, for he was the older, and might claim the first choice. Then, too, God had promised all the land to Abram, so that he might have said to Lot, "Go away, for this land is all mine." But Abram showed a kind, good heart in giving to Lot his choice of the land.

And Lot looked over the land from the mountain where they were standing, and saw down in the valley the river Jordan flowing between green fields, where the soil was rich. He saw the cities of Sodom and Gomorrah upon the plain, near the head of the Dead Sea, into which the Jordan flows. And Lot said, "I will go down yonder to the plain."

And he went down the mountain to the plain, with his tents and his men, and his flocks of sheep and his cattle, leaving the land on the mountains, which was not so good, to his uncle Abram. Perhaps Lot did not know that the people in Sodom were the most wicked of all the people in the land; but he went to live near them, and gradually moved his tent closer to Sodom, until after a time he was living in that wicked city.

After Lot had separated from Abram, God said to Abram:

"Lift up your eyes from this place, and look east and west, and north and south. All the land that you can see, mountains and valleys and plains, I will give it to you, and to your children, and their children, and those who come after them. Your descendants shall have all this land, and they shall be as many as the dust of the earth; so that if one could count the dust of the earth, they could as easily count those who shall come from you. Rise up, and walk through the land wherever you please, for it is all yours."
