Leviticus 7:15-17

King James Version

¹⁵ And the flesh of the sacrifice of his peace offerings for thanksgiving shall be eaten the same day that it is offered; he shall not leave any of it until the morning.

¹⁶ But if the sacrifice of his offering be a vow, or a voluntary offering, it shall be eaten the same day that he offereth his sacrifice: and on the morrow also the remainder of it shall be eaten:

¹⁷ But the remainder of the flesh of the sacrifice on the third day shall be burnt with fire.
