Commentary for Genesis 19:20

העיר הזאת קרובה THIS CITY IS NEAR — Its settlement as a city is near in point of time — it has been populated quite recently and therefore its measure is not yet filled (Shabbat 10b). And how recent was its settlement? It dated from the generation of the Dispersal of Nations, when mankind was scattered and men began to settle down each in his own place. This took place in the year when Peleg died, and from that time until now was fifty-two years, because Peleg died when Abraham was 48 years old. How is this? Peleg lived after he begat Reu 209 years (11:19): deduct from this number the 32 years that Reu was old when Serug was born (v. 22) and the 30 from the birth of Serug until the birth of Nahor (v. 22) giving 62, and from the birth of Nahor until Terah was born (v. 24) 29, giving 91, and from then until Abraham’s birth 70, giving a total of 161. Add 48 years of Abraham’s life and you have the 209. That was the year of the Dispersion. When Sodom was destroyed Abraham was 99 years old, so that from the Generation of the Dispersal (in the 48th year of Abraham’s life) until this time was 52 years. The colonisation of Zoar took place one year later than that of Sodom and its sister cities. To this fact reference is made in the words אמלטה נא “let me escape נא” i.e. let me escape to the city which is (נ''א (51 in numerical value.

הלא מצער היא, its population is small and you can afford to leave them untouched for now, seeing that there are not many sinners.

הנה העיד הזאת קרובה, "This town is nearby, etc." The verse is difficult. If the inhabitants of that town were guilty, what difference did it make that it was close by? Moreover, how could the angel say: "I have granted your wish?" Since when was it up to him? If the town was innocent, who had given the angel permission to destroy it even if Lot had not pleaded on its behalf?
