Exodus 12:14–20

^14–16“This will be a memorial day for you; you will celebrate it as a festival to God down through the generations, a fixed festival celebration to be observed always. You will eat unraised bread (matzoth) for seven days: On the first day get rid of all yeast from your houses—anyone who eats anything with yeast from the first day to the seventh day will be cut off from Israel. The first and the seventh days are set aside as holy; do no work on those days. Only what you have to do for meals; each person can do that.

^17–20“Keep the Festival of Unraised Bread! This marks the exact day I brought you out in force from the land of Egypt. Honor the day down through your generations, a fixed festival to be observed always. In the first month, beginning on the fourteenth day at evening until the twenty-first day at evening, you are to eat unraised bread. For those seven days not a trace of yeast is to be found in your houses. Anyone, whether a visitor or a native of the land, who eats anything raised shall be cut off from the community of Israel. Don’t eat anything raised. Only matzoth.”
