Why should we have salt on the table by our meals ?
Tosfos , Brochos 40a , cites a Medrash that the Satan may criticize Jews waiting for each other to wash without doing Mitzvos.
Thus Salt will protect us.
How do we understand this ?
Salt consists of 2 ingredients that are poison when separate , but together they are beneficial. That is the message of salt. Work together & do good deeds.
Now may be a good time for a gem of Torah study.
