Do not offer the blood of a sacrifice to Me along with anything leavened, and do not let any of the sacrifice from the Passover Feast remain until morning.
KJV
Thou shalt not offer the blood of my sacrifice with leaven; neither shall the sacrifice of the feast of the passover be left unto the morning.
ASV
Thou shalt not offer the blood of my sacrifice with leavened bread; neither shall the sacrifice of the feast of the passover be left unto the morning.
