 The feast began with the Paschal meal shortly after sunset on the evening of the 14th of Nisan, the first month of the Hebrew year, and went on for a further seven days. During this time no yeast was used in baking bread. Once it became known as the Azimes or Days of Unleavened Bread, all yeast was removed from the houses in the evening of the 14th. In this way the Hebrew people recalled that sudden exodus from the land in which they had suffered so much.
