Thousands of years ago when Temple stood in Jerusalem, sacrifices were brought as an atonement for sin. The Bible commands these sacrifices to be salted. Today, the Temple in Jerusalem no longer stands. In substitute, Jewish tradition views tables in private homes as symbolic altars at which we can worship God. If tables symbolize alters and bread is considered an offering to God, then it is only right that bread is salted before eating in accordance with Leviticus 2:13.
