"Nor shall any part of the meat which you sacrificed on the first day at evening remain all night until the morning"—Deuteronomy 16:4.
It is forbidden to leave over of the meat of the Festival Offering that is sacrificed on the fourteenth of Nissan [the eve of Passover] until the third morning, i.e., the morning of the sixteenth of Nissan. Rather it must be eaten within the two days allotted for this purpose.
