“You must not offer the blood of my sacrifice with yeast; the sacrifice from the Feast of Passover must not remain until the following morning.

It must be eaten on the day of your sacrifice and on the following day, but what is left over until the third day must be burned up.

They must not leave any of it until morning, nor break any of its bones; they must observe it in accordance with every statute of the Passover.
