What are the differences between the pesach offered in Egypt and the pesach-offering of [succeeding] generations? —- The purchase of the Egyptian pesach was on the tenth [of Nissan], it required sprinkling [of its blood] with a bundle of hyssop upon the lintel and upon the two doorposts, and was eaten in haste, during one night; but the Pesach of [succeeding] generations is observed all seven days.
