Leviticus 19:7

And if it be eaten at all on the third day, it is abominable; it shall not be accepted.

Cross-reference

Leviticus 7:18-21 gives the same law: eating peace offering on third day makes it unacceptable and the eater bears guilt. A direct parallel.

Leviticus 7:17 directly states that leftover flesh on the third day must be burned—the same regulation from the earlier peace offering instructions.

Leviticus 22:30 requires thanksgiving offerings to be eaten the same day—a similar no-leftovers rule but for a different sacrifice.

Isaiah 1:13 Parallel

Isaiah 1:13 uses the same term 'abomination' to reject vain offerings, echoing the principle that improper sacrifices are unacceptable.

Isaiah 66:3 Parallel

Isaiah 66:3 declares that even proper sacrifices are abominable when offered with a wicked heart, a broader rejection than here.
