And the sons of Israel who were found at Jerusalem kept the solemnity of unleavened bread for seven days with great rejoicing, praising the Lord throughout each day, with the Levites and the priests, accompanied by the musical instruments corresponding to their office.
You shall keep the solemnity of unleavened bread. For seven days, you shall eat unleavened bread, just as I instructed you, in the time of the month of what is new. For in the month of springtime you departed from Egypt.
But you shall offer a sacrifice with fire, for seven days, to the Lord. Then the seventh day shall be more honored and more holy; and you shall do no servile work in it.
