Genesis 12.10 - 13.13

Now there was a famine in the land; so Abram went down to Egypt to sojourn there, for the famine was severe in the land. It came about when he came near to Egypt, that he said to Sarai his wife, "See now, I know that you are a beautiful woman; and when the Egyptians see you they will say, 'This is his wife'; and they will kill me, but they will let you live. Please say that you are my sister so that it may go well with me because of you, and that I may live on account of you. It came about when Abram came into Egypt, the Egyptians saw that the woman was very beautiful. Pharaoh's officials saw her and praised her to Pharaoh; and the woman was taken into Pharaoh's house. Therefore he treated Abram well for her sake; and gave him sheep and oxen and donkeys and male and female servants and female donkeys and camels.

But the Lord struck Pharaoh and his house with great plagues because of Sarai, Abram's wife. Then Pharaoh called Abram and said, "What is this you have done to me? Why did you not tell me that she was your wife? Why did you say, 'She is my sister,' so that I took her for my wife? Now then, here is your wife, take her and go." Pharaoh commanded his men concerning him; and they escorted him away, with his wife and all that belonged to him.

So Abram went up from Egypt to the Negev, he and his wife and all that belonged to him, and Lot with him.

Now Abram was very rich in livestock, in silver and in gold. He went on his journeys from the Negev as far as Bethel, to the place where his tent had been at the beginning, between Bethel and Ai, to the place of the altar which he had made there formerly; and there Abram called on the name of the Lord. Now Lot, who went with Abram, also had flocks and herds and tents. And the land could not sustain them while dwelling together, for their possessions were so great that they were not able to remain together. And there was strife between the herdsmen of Abram's livestock and the herdsmen of Lot's livestock. Now the Canaanite and the Perizzite were dwelling then in the land.

So Abram said to Lot, "Please let there be no strife between you and me, nor between my herdsmen and your herdsmen, for we are brothers. Is not the whole land before you? Please separate from me; if to the left, then I will go to the right; or if to the right, then I will go to the left." Lot lifted up his eyes and saw all the valley of the Jordan, that it was well watered everywhere - this was before the Lord destroyed Sodom and Gomorrah - like the garden of the Lord, like the land of Egypt as you go to Zoar. So Lot chose for himself all the valley of the Jordan, and Lot journeyed eastward. Thus they separated from each other. Abram settled in the land of Canaan, while Lot settled in the cities of the valley, and moved his tents as far as Sodom. No the men of Sodom were wicked exceedingly and sinners against the Lord.
