This chapter contains parts of two stories: god telling Abrahan (formerly Abram) that he would have a son despite the couple were old, and the intention of god to plan a mass murder (version 18 onwards).
The interesting thing I can note here is that Abraham seemed to be of higher moral standard than god. At least he was able to ask if it would be just to kill all the people in a whole town if there were still 'righteous' men in town.
Another interesting, and very disturbing observation I can made is that god was much crueler than Abraham - "As soon as He had finished speaking to Abraham the LORD departed, and Abraham returned to his place.". God was NOT interested in sparing the town for less than 10 righteous men!
What is the moral of this story?
