In the first month, on the fourteenth day of the month at evening, you shall eat unleavened bread [and continue] until the twenty-first day of the month at evening.
Purge (clean out) the old leaven that you may be fresh (new) dough, still uncontaminated [as you are], for Christ, our Passover [Lamb], has been sacrificed.
And you shall keep it until the fourteenth day of the same month; and the whole assembly of the congregation of Israel shall [each] kill [his] lamb in the evening.
