If the two angels are the same as the men that met with Abraham, then one of them must have bailed out on the way. Maybe this was the man that the Lord had appeared as and He left the angels to do the rest of the work. These men catch the eye of Lot, just like they did Abraham, and Lot is apparently the only man in the entire place that want to “know” them. The town of Sodom does these angels the favor of showing their sin. Since every single man in the town (except Lot’s sons-in-law perhaps) shows up, this eliminates the chance of finding ten righteous. We then find out in Genesis 19 that angels have some power here on earth and are probably very little like the nude Precious Moments angels.
As for Lot, it is pretty horrible to think that he would offer his daughters to the crowds, but maybe it shows faithfulness too. Thought if it were faithfulness, he probably wouldn’t have tried to appease the crowd, but stood up to them and trusted the Lord to deal with him and them accordingly. When the angels are trying to get Lot out of the city, I was a bit annoyed at Lot’s constant questioning and begging to do something else besides what they told him. Then I thought about how I would react if I were told to flee from my house immediately. I would definitely be as unprepared as Lot.
The last part of this chapter is slightly awkward. I don’t have maternal instincts (being not a woman), so I am not sure if starving them can lead you to do such crazy things. My guess is that these two people groups that come from this act were relevant to the people at the time, so it would be good for them to know where they came from. I do wonder what Lot said when he found out his daughters were mysteriously impregnated.
