'Third' in the Bible

But if any of the flesh of the offering is still unused on the third day, it is to be burned with fire.

And if any of the flesh of the peace-offering is taken as food on the third day, it will not be pleasing to God and will not be put to the account of him who gives it; it will be unclean and a cause of sin to him who takes it as food.

Let it be used for food on the same day on which it is offered, or on the day after; and whatever is over on the third day is to be burned with fire.

If any of it is used for food on the third day, it is a disgusting thing and will not be pleasing to the Lord.
