Comentario citado sobre I Reyes 18:13

והיה המחנה הנשאר לפליטה, “then the remaining camp would survive.” The second camp contained Rachel, Leah, and their respective children. In order to explain this verse completely, we have to understand it as follows: “Yaakov divided the children to Rachel and Leah respectively and to the two maid-servants and their children respectively in order for them to survive attempted murder by Esau.” The expression לפליטה occurs in that sense in Jeremiah 51,50 פליטים מחרב, “fugitives from the sword.” This verse is also the source which taught the prophet Ovadiah to divide the fledgling prophets whom he hid by separating them into two groups, each in a different cave. This is why Jeremiah wrote in Kings I 18,13 quoting Ovadiah: “I have hidden 100 of the Lord’s prophets, 50 each per cave; and I have fed them bread and provided them with water.” Our sages in Baba Metzia, basing themselves on our verse, made the rule that a person is well advised to diversify his wealth into three types of investments. 1) land. 2) commerce; 3) ready cash or easily convertible and immediately accessible assets. They also base this on Deut. 28,8 “G’d will command His blessing for you in your storehouses.” The “storehouses” are a reference to warehouses serving as the place where the merchant keeps his stock-in-trade. The next words in that verse ובכל משלח ידיך, “and your every undertaking,“ are understood as a reference to ready cash or otherwise easily cashable assets. The last expression in the above verse, i.e. וברכך בארץ, “and He will bless you on the land,” refers to G’d blessing one’s investment in land (for agriculture).
