First Reading: Genesis 13:2, 5-18

² Now Abram was very rich in cattle, in silver, and in gold.
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 cattle and the herdsmen of Lot’s cattle. At that time the Canaanites and the Per’izzites dwelt 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 Zo’ar; this was before the LORD destroyed Sodom and Gomor’rah.
¹¹ So Lot chose for himself all the Jordan valley, and Lot journeyed east; thus they separated from each other.
¹² Abram dwelt in the land of Canaan, while Lot dwelt 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.
¹⁴ The LORD said to Abram, after Lot had separated from him, “Lift up your eyes, and look from the place where you are, northward and southward and eastward and westward;
¹⁵ for all the land which you see I will give to you and to your descendants for ever.
¹⁶ I will make your descendants as the dust of the earth; so that if one can count the dust of the earth, your descendants also can be counted.
¹⁷ Arise, walk through the length and the breadth of the land, for I will give it to you.”
¹⁸ So Abram moved his tent, and came and dwelt by the oaks of Mamre, which are at Hebron; and there he built an altar to the LORD.
