13:1 So Abram went up from Egypt, he and his wife and all that he had, and Lot with him, into the Negeb.
2 Now Abram was very rich in livestock, in silver, and in gold. 3 And he journeyed on from the Negeb as far as Bethel to the place where his tent had been at the beginning, between Bethel and Ai, 4 to the place where he had made an altar at the first. And there Abram called upon the name of the Lord. 5 And Lot, who went with Abram, also had flocks and herds and tents, 6 so that the land could not support both of them dwelling together; for their possessions were so great that they could not dwell together, 7 and there was strife between the herdsmen of Abram's livestock and the herdsmen of Lot's livestock. At that time the Canaanites and the Perizzites were dwelling in the land.
8 Then Abram said to Lot, “Let there be no strife between you and me, and between your herdsmen and my herdsmen, for we are kinsmen. 9 Is not the whole land before you? Separate yourself from me. If you take the left hand, then I will go to the right, or if you take the right hand, then I will go to the left.” 10 And Lot lifted up his eyes and saw that the Jordan Valley was well watered everywhere like the garden of the Lord, like the land of Egypt, in the direction of Zoar. (This was before the Lord destroyed Sodom and Gomorrah.) 11 So Lot chose for himself all the Jordan Valley, and Lot journeyed east. Thus they separated from each other. 12 Abram settled in the land of Canaan, while Lot settled among the cities of the valley and moved his tent as far as Sodom. 13 Now the men of Sodom were wicked, great sinners against the Lord.

15 As morning dawned, the angels urged Lot, saying, “Up! Take your wife and your two daughters who are here, lest you be swept away in the punishment of the city.” 16 But he lingered. So the men seized him and his wife and his two daughters by the hand, the Lord being merciful to him, and they brought him out and set him outside the city. 17 And as they brought them out, one said, “Escape for your life. Do not look back or stop anywhere in the valley. Escape to the hills, lest you be swept away.” 18 And Lot said to them, “Oh, no, my lords. 19 Behold, your servant has found favor in your sight, and you have shown me great kindness in saving my life. But I cannot escape to the hills, lest the disaster overtake me and I die. 20 Behold, this city is near enough to flee to, and it is a little one. Let me escape there—is it not a little one?—and my life will be saved!” 21 He said to him, “Behold, I grant you this favor also, that I will not overthrow the city of which you have spoken. 22 Escape there quickly, for I can do nothing till you arrive there.” Therefore the name of the city was called Zoar.
