Why Dip Bread in Salt?
I was at a Shabbat dinner last week and after they ate the challah, they dipped it into salt. I know there must be a reason, but I was too shy to ask.
The Aish Rabbi Replies:
Every time we eat bread we should dip the first bite into salt, not only on Shabbat, The reason for this custom is because the table that we eat on is compared to the Altar that once stood in the Holy Temple. The home is likened to a miniature Temple. Just as all offerings on the Altar were salted, the bread that we eat is salted, too.
Also we place salt on the bread because salt is a preserver, symbolizing that this meal is no longer merely a transitory experience, but a moment that will last for eternity.
Further, Genesis 3:19 says that we should eat our bread with the sweat of our brow (sweat contains salt).
The Torah (Leviticus 2:13) speaks of a "Covenant of Salt," where God instructs us to use salt on all the offerings as if to say that His covenant with us is eternal, sealed with salt. Since salt never spoils, it is a symbol of indestructibility.
