Among the laws and observances associated with the events of this chapter are: 1. The law ordaining the first of Nisan, as the "New Year for months", in commemoration of the inauguration of the new era in Israel's history; 2. the annual sacrifice of the Paschal lamb which was eaten in the family circle together with bitter herbs and unleavened bread to recall the similar observances of the Israelites before leaving Egypt;[9] 3. the celebration for seven days[10] of the festival of Passover by the previous removal of all leaven and abstention from it during the festival and by the eating of unleavened bread in commemoration of the haste of Israel's departure that did not allow them to make other provision; 4. the duty of narrating these events to one's children, which gave rise to the recital of the Haggadah on the night of Passover; 5. the sanctification of the first-born of cattle and of men in recognition of the providential character of the tenth plague, the latter custom surviving in the practice of "pidyon ha-ben", "the redemption of the first-born", and, 6. the injunction to make of this command "a sign upon thy hand and frontlets between thine eyes" which led to the inclusion of the passage containing these words, and the command to sanctify the first-born among those enclosed in the _tephillin_, thus making them a theme for daily reflection. In addition to these practices, it is noteworthy that the Sabbath and holidays, even those having other historic associations, are characterized in our liturgy as מִצְרַים לִיצִואַת זֵכֶר "memorials of the Exodus from Egypt." The multitude of observances that are thus designed to keep us mindful of the Exodus testify to the importance of the leading idea associated with this event for the Jewish people at all times, namely, the identification of the cause of Israel with the cause of God, "And I will take you to Me for a people, and I will be to you a God, and ye shall know that I am the Lord, your God, who brought you out from under the burdens of the Egyptians." (Exodus 6. 7.) [9] Since the sacrifices have ceased with the destruction of the Temple, the eating of the meal as part of the Seder service answers this purpose. At this meal the Paschal lamb is symbolically represented by the roasted bone, and the _maẓẓot_ and _maror_ are eaten.
