‘No grain offering which you bring to the Lord shall be made with leaven, for you shall burn no leaven nor any honey in any offering to the Lord made by fire.
And no leaven shall be seen among you in all your territory for seven days, nor shall any of the meat which you sacrifice the first day at twilight remain overnight until morning.
‘The flesh of the sacrifice of his peace offering for thanksgiving shall be eaten the same day it is offered. He shall not leave any of it until morning.
If he offers it for a thanksgiving, then he shall offer, with the sacrifice of thanksgiving, unleavened cakes mixed with oil, unleavened wafers anointed with oil, or cakes of blended flour mixed with oil.
Seven days you shall eat unleavened bread. On the first day you shall remove leaven from your houses. For whoever eats leavened bread from the first day until the seventh day, that person shall be cut off from Israel.
And if any of the flesh of the consecration offerings, or of the bread, remains until the morning, then you shall burn the remainder with fire. It shall not be eaten, because it is holy.
