In the basic text in Bereshis 13:5-18, the shepherds of Abraham and Lot were fighting because there wasn't enough space for them. Rashi expands a little bit more on these pesukim. He says that the only reason that Lot had all of his possessions was because he was with Abraham. He was with Abraham when he went down to Egypt and he ended up with a large amount of possessions because when Pharaoh sent them away, he sent them with money, animals, food, and much more. Rashi also states that Lot's shepherds were evil and they would let their animals graze wherever they wanted, even if it meant they would graze in a privately owned field. Abraham's shepherd's, however, were righteous and they would say to Lot's shepherds that what they were doing was wrong. They responded that god said that the land would belong to Abraham and Lot would inherit the land from Abraham because he had no sons so it would go to Lot, his nephew. However, the shepherds didn't understand that it didn't belong to Abraham yet; it still belonged to the Canaanite and Prizite nations that lived there.
Once Abraham saw that there was a problem, he proposed a solution. He proposed that they split up. Lot went westward to a city called Sdom. Rashi says that he went there for many reasons. Firstly, he was close to Abraham so just in case he needed protection, he wouldn't be too far away. Secondly, he chose it because it was very good for agriculture. There were plains and rivers where he could grow plants and trees. However, by separating himself from Abraham, he also separated himself from god. Sdom was a place with very bad people. They were people who sinned and they wanted to rebel against god. It was good for Abraham that Lot separated from him because he was a bad influence. We learn this by seeing that right after Lot left, Abraham gets a prophecy from god. Abraham didn't receive any prophecies all the time that Lot was living with him, and once he left god began to tell Abraham about the nation that would come from him.
The Ramban expands on what Rashi said. Rashi stated that Lot’s shepherds thought that the land would eventually belong to them and since they had so many possessions, it would be okay to take from fields that currently had owners. Their mistake was that the land was meant for Abraham and not Lot. Abraham was afraid that since they had so many possessions, the people of the land would hear about them and drive them out of the land. When it says in the pasuk that there wasn’t enough land for Abraham and Lot, it meant for Abraham and Lot, who had such a large amount of possessions, and the nations who were already living there. To solve this problem, Abraham would re-locate every year so that his sheep and cattle would graze in different areas in the land so as not to take advantage of one specific region. When Abraham and Lot separated, Lot lived in one place, on the banks of the Jordan River, and Abraham continued to re-locate every year but he never went near the area where Lot was living.
The next perek that speaks about Lot shows that he has grown into a very materialistic person since he left Abraham to go live in Sdom. In perek 14 there is a war between the 4 kings and the 5 kings. The war was basically about materialistic possessions. During this war, Lot was taken captive and Abraham organized and army to go and save Lot. This could be taken metaphorically to mean save him from materialism. Even after Abraham saved Lot, he continued to live in Sdom. Along with saving Lot, Abraham also saved the possessions of the 5 kings that were lost to the 4 kings in the war. When he was given a part of the possessions as a reward, he refused it and said that all of the possessions should go back to the people that they belong to.
Out of all the relationships we spoke about so far in class, this one was basically the only one that didn't have a large fight in it. Instead it was resolved peacefully. May we all have peaceful and successful relationships throughout our lives. Shalom V'lehitraot!
