Genesis 19:26

“But his wife looked back from behind him, etc.] That is, the wife of Lot, whose name the Jewish writers f1171 say was Adith, or as others Irith f1172 ; and, according to the Targums of Jonathan and Jerusalem, she was a native of Sodom: now, as they were going from Sodom to Zoar, she was behind Lot, his back was to her, so that he could not see her; this was a temptation to her to look back, since her husband could not see her; and this she did, either, as the above paraphrases suggest, that she might see what would be the end of her father’s house and family, or whether her married daughters, if she had any, were following her, after whom her bowels yearned; or being grieved for the goods…”

“Lot was accompanied by his wife and two daughters. But whether it was from irresistible curiosity or perturbation of feeling, or that she was about to return to save something, his wife lingered, and while thus disobeying the parting counsel, "to look not back, nor stay in all the plain" [Gen 19:17], the torrent of liquid lava enveloped her so that she became the victim of her supine indolence or sinful rashness.”

“- The Destruction of Sodom and Amorah 9. גשׁ־הלאה gesh-hāl'âh, “approach to a distant point,” stand back. 11. סנורים sanevērı̂ym, “blindness,” affecting the mental more than the ocular vision. 37. מואב mô'āb, Moab; מאב mē'āb, “from a father.” בן־עמי ben-‛amı̂y, Ben-‘ammi, “son of my people.” עמון ‛amôn, ‘Ammon, “of the people.” This chapter is the continuation and conclusion of the former. It records a part of God’s strange work - strange, because it consists in punishment, and because it is foreign to the covenant of grace. Yet it is closely connected with Abraham’s history, inasmuch as it is a signal chastisement of wickedness in his neighborhood, a memorial of the righteous…”

“19:26 looked back: The verb indicates prolonged, intense gazing toward the world she loved, not a curious glance (15:5; Exod 33:8; Num 21:9; 1 Sam 2:32; cp. Exod 3:6). Lot’s wife was too attached to Sodom to follow God’s call of grace, so she was included in the judgment as she lingered on the valley slopes. Christ’s return to judge the world will be as sudden and devastating as the destruction of Sodom (Luke 17:32-37). Those who crave the life of this wicked world will lose this world and the next.”
