And ye shall let nothing of it remain until the morning; and that which remaineth of it until the morning ye shall burn with fire.

Neither shall there remain any thing of it until morning. If there be any thing left, you shall burn it with fire.

And ye shall let none of it remain until the morning; and what remaineth of it until the morning ye shall burn with fire.

and ye do not leave of it till morning, and that which is remaining of it till morning with fire ye do burn.

Do not keep any of it till the morning; anything which is not used is to be burned with fire.

Neither shall there remain anything from it until morning. If anything will have been left over, you shall burn it with fire.

Nec residuum facietis quicquam ex eo usque mane: quod autem reliquum fuerit ex eo usque mane, comburetis.

This was afterward a general law of sacrifices; at once preventing all possibility of profanity, and of superstitious abuse. The injunction is on both accounts justly applied by our Church to the eucharist.
Burn with fire - Not being consumed by man, it was thus offered, like other sacrifices Exodus 12:8, to God.

Ye shall let nothing of it remain until the morning - Merely to prevent putrefaction; for it was not meet that a thing offered to God should be subjected to corruption, which in such hot countries it must speedily undergo. Thus the body of our blessed Lord saw no corruption, Psalm 16:10; Acts 2:27, because, like the paschal lamb, it was a sacrifice offered to God.
It appears that from the Jewish passover the heathens borrowed their sacrifice termed Propter Viam. It was their custom previously to their undertaking a journey, to offer a sacrifice to their gods, and to eat the whole if possible, but if any part was left they burned it with fire; and this was called propter viam, because it was made to procure a prosperous journey. It was in reference to this that Cato is said to have rallied a person called Q. Albidius, who, having eaten up all his goods, set fire to his house, his only remaining property. "He has offered his sacrifice propter viam," says Cato, "because he has burned what he could not eat." This account is given by Macrobius, Saturn., lib. ii., 2, edit. Bipont., vol. 1, p. 333; and is a remarkable instance how closely some of the religious observances of the people of God have been copied by the heathen nations.

And ye shall let nothing of it remain until the morning,.... It was to be all ate up; a whole Christ is to be received and fed upon by faith; Christ in both his natures, divine and human, united in his person, in all his offices of prophet, priest, and King, and with all the benefits and blessings of his grace, and which come by his blood, righteousness, and sacrifice:
and that which remaineth of it until the morning, ye shall burn with fire: what of the flesh which remaineth not ate, and what of it that could not be eaten, as the bones, which were not broken, and the nerves and sinews, which might not be eaten; and so runs the Jewish canon (d),"the bones, and the sinews, and what remains, they shall burn on the sixteenth day; and if the sixteenth happens on the sabbath, they shall burn on the seventeenth.''The reason of this law was, that what was left might not be converted to common or superstitious uses, as also that the Israelites might not be burdened with it in their journey, nor the Egyptians have an opportunity of treating it with contempt.
(d) Misn. ut supra, (Persch. c. 7.) sect. 10.

let nothing of it remain until the morning--which might be applied in a superstitious manner, or allowed to putrefy, which in a hot climate would speedily have ensued; and which was not becoming in what had been offered to God.

Ye shall burn with fire - To prevent the profane abuse of it.
