Moses the Purple Seller and the Passover of the Fathers

Another interpretation: To what may the matter be compared? To one who was selling purple cloth and was crying out, saying, "Here is purple!" The king peered out and heard his voice, called him, and said to him, "What are you selling?" He said, "Nothing at all." He said to him, "I heard your voice saying, Here is purple, and you say nothing at all?" He said to him, "My lord, it is purple, but next to you it is nothing." So too Moses: next to the Holy One, blessed be He, who created the mouth and speech, he said, "I am not a man of words"; but next to Israel, "These are the words." All seven days the Holy One, blessed be He, was speaking with Moses from within the bush, as it is said, "neither yesterday nor the day before, nor since You spoke" (Exodus 4:10). And it was the season of Passover, and at that same time the following year, on the fifteenth of Nisan, Israel went out from Egypt. On the fifteenth of Nisan Isaac was born. On the fifteenth of Nisan Sarah was given the good tidings. On the fifteenth of Nisan it was spoken with Abraham our father at the Covenant Between the Pieces, as it is said (Exodus 12:41), "and it came to pass at the end" - one end for them all. On the fourteenth they slaughtered their Passover offerings, and it was the fourth day of the week. On that night the firstborn were struck. The next day they journeyed from Rameses, and on the fourth day, "and it was told to the king of Egypt" (Exodus 14:5). On the fifth and sixth they pursued. At dawn they sang the Song, and it was the fourth day of the week, and it was the last festival day of Passover.
