Round Pomegranates Challah covers CAT# CME - 4. Machine embroidered Challah covers using various colors of silk, gold and silver threads. Size: 20" x 16" .The placement of the challah under the challah cover and over the Shabbat tablecloth (or over a challah cutting board) also recalls the Biblical scene of the manna which the Israelites ate every day following the Exodus from Egypt. When Moses told the people about the manna, he said that it would fall for them every day of the week. However, in deference to the holiness of Shabbat, the manna would not fall on that day. Instead, two portions of manna would fall on Friday, enough for that day and for the Shabbat (Exodus 16:22-26). This is given as the reason for the use of two braided loaves at Shabbat and holiday meals, as the challahs represent the double portion of manna that fell in honor of Shabbat.Each morning the Israelites found the manna in the fields, encased in two layers of dew to preserve its freshness. Rashi describes the way the manna was found: Thus we see that the dew fell upon the ground and the manna fell upon it, and then dew fell again upon this, and so it was as though it were carefully packed in a chest (Rashi on Exodus 16:13, quoting Mechilta, Yoma 75b). Thus, we place the challahs beneath a challah cover and over a tablecloth (or challah board) to recreate the miracle of the manna at our own Shabbat tables.
