Boyd’s Bible Dictionary:

(veil). Abraham’s nephew (Gen. 11:27-3127Now these are the generations of Terah: Terah begat Abram, Nahor, and Haran; and Haran begat Lot. 28And Haran died before his father Terah in the land of his nativity, in Ur of the Chaldees. 29And Abram and Nahor took them wives: the name of Abram's wife was Sarai; and the name of Nahor's wife, Milcah, the daughter of Haran, the father of Milcah, and the father of Iscah. 30But Sarai was barren; she had no child. 31And Terah took Abram his son, and Lot the son of Haran his son's son, and Sarai his daughter in law, his son Abram's wife; and they went forth with them from Ur of the Chaldees, to go into the land of Canaan; and they came unto Haran, and dwelt there. (Genesis 11:27‑31)). Settled in Jordan valley (Gen. 13:1-131And Abram went up out of Egypt, he, and his wife, and all that he had, and Lot with him, into the south. 2And Abram was very rich in cattle, in silver, and in gold. 3And he went on his journeys from the south even to Beth-el, unto the place where his tent had been at the beginning, between Beth-el and Hai; 4Unto the place of the altar, which he had made there at the first: and there Abram called on the name of the Lord. 5And Lot also, which went with Abram, had flocks, and herds, and tents. 6And the land was not able to bear them, that they might dwell together: for their substance was great, so that they could not dwell together. 7And there was a strife between the herdmen of Abram's cattle and the herdmen of Lot's cattle: and the Canaanite and the Perizzite dwelled then in the land. 8And Abram said unto Lot, Let there be no strife, I pray thee, between me and thee, and between my herdmen and thy herdmen; for we be brethren. 9Is not the whole land before thee? separate thyself, I pray thee, from me: if thou wilt take the left hand, then I will go to the right; or if thou depart to the right hand, then I will go to the left. 10And Lot lifted up his eyes, and beheld all the plain of Jordan, that it was well watered every where, before the Lord destroyed Sodom and Gomorrah, even as the garden of the Lord, like the land of Egypt, as thou comest unto Zoar. 11Then Lot chose him all the plain of Jordan; and Lot journeyed east: and they separated themselves the one from the other. 12Abram dwelled in the land of Canaan, and Lot dwelled in the cities of the plain, and pitched his tent toward Sodom. 13But the men of Sodom were wicked and sinners before the Lord exceedingly. (Genesis 13:1‑13)). Escaped to mountains (Gen. 19). Progenitor of Moabites and Ammonites.

Concise Bible Dictionary:

Son of Haran the brother of Abraham. He seems to have accompanied Abraham without having a like faith in Abraham’s God. When their flocks and herds had so increased that they could no longer dwell together, Abraham bade his nephew choose where he would turn. Lot looked on the well-watered plain of the Jordan, and went toward Sodom, notwithstanding that the men of that city were exceedingly wicked. The next record of Lot is that he dwelt in Sodom, and from thence was carried away by the four kings who made war against that city.
Though rescued by Abraham he did not profit by the discipline, but returned to dwell in the guilty city; whereas Abraham would not accept so much as a shoe latchet from its king. Lot is next seen sitting in the gate of Sodom, the place of power and judgment, when the two angels arrived to destroy the city. He acted hospitably towards them, but had to be rescued by them from the enmity of the inhabitants.
Lot and his family were loth to leave the city, but the angels hastened them out, and bade them flee to the mountains. Lot begged to be allowed to go to Zoar, and was permitted; but, fearing to stay there, he left with his two daughters and abode in a cave, where, alas, he became the father of Moab and Ben-ammi, the ancestors of the Moabites and the Ammonites, who are afterward alluded to as the children of Lot.
From his history in the Old Testament it could not have been discovered that he was a righteous man; but this testimony is given of him in 2 Peter 2:7-87And delivered just Lot, vexed with the filthy conversation of the wicked: 8(For that righteous man dwelling among them, in seeing and hearing, vexed his righteous soul from day to day with their unlawful deeds;) (2 Peter 2:7‑8), where he is called “just Lot,” who, as a righteous man, was daily vexed in his soul by the unlawful deeds of those among whom he dwelt. Though God delivered him, he is a solemn instance of a righteous man dwelling needlessly amid gross wickedness; his course being the strongest contrast to that of Abraham (Gen. 11-14, 19; Psa. 83:88Assur also is joined with them: they have holpen the children of Lot. Selah. (Psalm 83:8); Luke 17:28-2928Likewise also as it was in the days of Lot; they did eat, they drank, they bought, they sold, they planted, they builded; 29But the same day that Lot went out of Sodom it rained fire and brimstone from heaven, and destroyed them all. (Luke 17:28‑29)).
LOT’S WIFE, on leaving Sodom, looked back and became a pillar of salt and is held up as a warning not to linger but to flee from coming judgments (Luke 17:3232Remember Lot's wife. (Luke 17:32)).
