“Do not offer the blood of a sacrifice to me with anything containing yeast, and do not leave any of the sacrifice of the Feast of Passover until the next morning.
“ ‘Every grain offering you bring to the Lord must be made without yeast, because you must not burn any yeast or honey in an offering made by fire to the Lord.
When the fellowship offering is given to thank the Lord, the meat from it must be eaten the same day it is offered; none of it must be left until morning.
Then Jesus told another story: “The kingdom of heaven is like yeast that a woman took and hid in a large tub of flour until it made all the dough rise.”
Do not eat it with bread made with yeast. But for seven days eat bread made without yeast, the bread of suffering, because you left Egypt in a hurry. So all your life you will remember the time you left Egypt.
There must be no yeast anywhere in your land for seven days. Offer the sacrifice on the evening of the first day, and eat all the meat before morning; do not leave it overnight.
