14 “‘This day will become a memorial for you, and you will celebrate it as a festival to the Lord—you will celebrate it perpetually as a lasting ordinance. 15 For seven days you must eat bread made without yeast. Surely on the first day you must put away yeast from your houses because anyone who eats bread made with yeast from the first day to the seventh day will be cut off from Israel. 16 “‘On the first day there will be a holy convocation, and on the seventh day there will be a holy convocation for you. You must do no work of any kind on them, only what every person will eat—that alone may be prepared for you. 17 So you will keep the Feast of Unleavened Bread, because on this very day I brought your regiments out from the land of Egypt, and so you must keep this day perpetually as a lasting ordinance. 18 In the first month, from the fourteenth day of the month, in the evening, you will eat bread made without yeast until the twenty-first day of the month in the evening. 19 For seven days yeast must not be found in your houses, for whoever eats what is made with yeast—that person will be cut off from the community of Israel, whether a resident foreigner or one born in the land. 20 You will not eat anything made with yeast; in all the places where you live you must eat bread made without yeast.’”

3 For even though I am absent physically, I am present in spirit. And I have already judged the one who did this, just as though I were present. 4 When you gather together in the name of our Lord Jesus, and I am with you in spirit, along with the power of our Lord Jesus, 5 hand this man over to Satan for the destruction of the flesh, so that his spirit may be saved in the day of the Lord. 6 Your boasting is not good. Don’t you know that a little yeast affects the whole batch of dough? 7 Clean out the old yeast so that you may be a new batch of dough—you are, in fact, without yeast. For Christ, our Passover lamb, has been sacrificed. 8 So then, let us celebrate the festival, not with the old yeast, the yeast of vice and evil, but with the bread without yeast, the bread of sincerity and truth.
