Challah covers - Pomegranates - Full CAT# CME - 10. Machine embroidered Challah covers using various colors of silk, gold and silver threads. Size: 20" x 16" .A matzo cover serves a slightly more enhanced function at the Passover Seder. While the matzos are covered during the Kiddush at the beginning of the Seder — similar to the way the challah is covered during the Kiddush at the beginning of a Shabbat or Yom Tov meal — the matzos are also covered and uncovered several times at designated points in the text of the Passover Haggadah. According to the Gemara, matzo is called lechem oni (poor man's bread); the Hebrew word oni can also be construed as "answers," yielding, "bread upon which answers are spoken."Thus, the matzos are uncovered during the telling of the story of the Jews' servitude in Egypt. However, when the wine cups are raised to express praise to God for the redemption, the matzos are covered so that they will not be "shamed", as one is giving preference to the wine. Matzo covers also differ from challah covers in that they can contain three "pockets" into which the three matzos (set out at the beginning of the Seder) are inserted.
