I've been reading Bereishit 19 in the Sefaria and Chabad translations, and I'm a little confused with the daughter situation. In verse 8, trying to protect his guests, Lot offers the Sodomites his two daughters "who have not known(Sefaria)/were not intimate with(Chabad) a man". Then, verse 14, there's a difference in the translations that has me confused. Lot speaks to his "sons-in-law" in a futile attempt to save their lives, who were either "the suitors of his daughters"(Chabad), or "had married his daughters"(Sefaria). Which was it? If they were just suitors/engaged, that would explain Lot's words in verse 8. But if they were actually married, then -- what? Was he just stalling for time(maybe recognizing and hoping for the angels' help?) by offering them virgin daughters? Did he actually have four daughters, two married and two virgins? Verse 15 doesn't seem to help, describing two "remaining daughters"(Sefaria), which could mean two of four total, or two daughters "who are here"(Chabad), which might mean either that there are just two and they were in the house during the incident or two in the house and two stayed with their unbelieving husbands.
How has this been historically understood in the literature - were there two (just engaged) or actually four daughters?
