SEV Biblia, Chapter 7:16
Mas si el sacrificio de su ofrenda fuere voto, o voluntario, el día que ofreciere su sacrificio será comido; y lo que de él quedare, se comerá al día siguiente;
John Gill's Bible Commentary
Ver. 16. But if the sacrifice of his offering be a vow , etc.] Be on account of a vow made, as, that if he was favoured with such and such benefits, or delivered out of such and such troubles and distresses, then he would offer such a sacrifice: or a voluntary offering ; without any condition or obligation; what from the mere motion of his mind he freely offered, not being directed to it by any command of God, or under any necessity from a vow of his own, and without any view to; any future good to be enjoyed: Aben Ezra describes both the one and the other thus; a “vow” which he uttered with his lips in his distresses, a “voluntary offering”, which his spirit made him willing to bring, a sacrifice to God neither for a vow nor for thanksgiving: it shall be eaten the same day that he offereth his sacrifice ; that is, it shall be begun to be eaten then, and if all is eaten up it is very well, but they were not obliged in either of these cases, as in the preceding, to eat up all, and leave none to the morning, for it follows: and on the morrow also the remainder of it shall be eaten ; some of it, if thought fit, and could not be conveniently eaten, might be kept till the day after the sacrifice, but no longer.
Matthew Henry Commentary
Verses 11-27 - As to the peace-offerings, in the expression of their sense of mercy God left them more at liberty, than in the expression of their sense of sin; that their sacrifices, being free-will offerings, might be the more acceptable, while, by obliging them to bring the sacrifices of atonement, God shows the necessity of the great Propitiation. The mai reason why blood was forbidden of old, was because the Lord ha appointed blood for an atonement. This use, being figurative, had it end in Christ, who by his death and blood-shedding caused the sacrifices to cease. Therefore this law is not now in force of believers.
