(1) Now, when King Amraphel of Shinar, King Arioch of Ellasar, King Chedorlaomer of Elam, and King Tidal of Goiim (2) made war on King Bera of Sodom, King Birsha of Gomorrah, King Shinab of Admah, King Shemeber of Zeboiim, and the king of Bela, which is Zoar, (3) all the latter joined forces at the Valley of Siddim, now the Dead Sea. (4) Twelve years they served Chedorlaomer, and in the thirteenth year they rebelled. (5) In the fourteenth year Chedorlaomer and the kings who were with him came and defeated the Rephaim at Ashteroth-karnaim, the Zuzim at Ham, the Emim at Shaveh-kiriathaim, (6) and the Horites in their hill country of Seir as far as El-paran, which is by the wilderness. (7) On their way back they came to En-mishpat, which is Kadesh, and subdued all the territory of the Amalekites, and also the Amorites who dwelt in Hazazon-tamar. (8) Then the king of Sodom, the king of Gomorrah, the king of Admah, the king of Zeboiim, and the king of Bela, which is Zoar, went forth and engaged them in battle in the Valley of Siddim: (9) King Chedorlaomer of Elam, King Tidal of Goiim, King Amraphel of Shinar, and King Arioch of Ellasar—four kings against those five. (10) Now the Valley of Siddim was dotted with bitumen pits; and the kings of Sodom and Gomorrah, in their flight, threw themselves into them, while the rest escaped to the hill country. (11) [The invaders] seized all the wealth of Sodom and Gomorrah and all their provisions, and went their way.

(5) Lot, who went with Abram, also had flocks and herds and tents, (6) so that the land could not support them staying together; for their possessions were so great that they could not remain together. (7) And there was quarreling between the herders of Abram’s cattle and those of Lot’s cattle.—The Canaanites and Perizzites were then dwelling in the land.— (8) Abram said to Lot, “Let there be no strife between you and me, between my herders and yours, for we are kin. (9) Is not the whole land before you? Let us separate: if you go north, I will go south; and if you go south, I will go north.” (10) Lot looked about him and saw how well watered was the whole plain of the Jordan, all of it—this was before יהוה had destroyed Sodom and Gomorrah—all the way to Zoar, like the garden of יהוה, like the land of Egypt. (11) So Lot chose for himself the whole plain of the Jordan, and Lot journeyed eastward. Thus they parted from each other; (12) Abram remained in the land of Canaan, while Lot settled in the cities of the Plain, pitching his tents near Sodom.
(27) Now this is the line of Terah: Terah begot Abram, Nahor, and Haran; and Haran begot Lot. (28) Haran died in the lifetime of his father Terah, in his native land, Ur of the Chaldeans. (29) Abram and Nahor took wives for themselves, the name of Abram’s wife being Sarai and that of Nahor’s wife Milcah, the daughter of Haran, the father of Milcah and Iscah. (30) Now Sarai was barren, she had no child. (31) Terah took his son Abram, his grandson Lot the son of Haran, and his daughter-in-law Sarai, the wife of his son Abram, and they set out together from Ur of the Chaldeans for the land of Canaan; but when they had come as far as Haran, they settled there. (32) The days of Terah came to 205 years; and Terah died in Haran.
Abraham is unique among humans because of his courage and defiance; it is these qualities that attract God to him as one with whom to covenant. The term 'ivri ("Hebrew") is first used to describe Abraham. The rabbis read it to mean "contrarian" - "the whole world stood on one side ['ever] and he on the other." Swimming against the stream will be essential to the Abrahamic legacy.

(14) When Abram heard that his kinsman’s [household] had been taken captive, he mustered his retainers, born into his household, numbering three hundred and eighteen, and went in pursuit as far as Dan. (15) At night, he and his servants deployed against them and defeated them; and he pursued them as far as Hobah, which is north of Damascus. (16) He brought back all the possessions; he also brought back his kinsman Lot and his possessions, and the women and the rest of the people.

(17) When he returned from defeating Chedorlaomer and the kings with him, the king of Sodom came out to meet him in the Valley of Shaveh, which is the Valley of the King. ... (21) [T]he king of Sodom said to Abram, “Give me the persons, and take the possessions for yourself.” (22) But Abram said to the king of Sodom, I swear to יהוה, God Most High, Creator of heaven and earth: (23) I will not take so much as a thread or a sandal strap of what is yours; you shall not say, ‘It is I who made Abram rich.’ (24) For me, nothing but what my servants have used up; as for the share of the parties who went with me—Aner, Eshkol, and Mamre—let them take their share.”
