Theodoret of Cyrus
Why does God prohibit the consumption of sacrifices after the third day, and why is there a punishment for those who violate this command, marked by His declaration that such a sacrifice loses its value? God desires that those who present offerings do not only partake in the celebration themselves but also share the food with those in need. Thus, He instructs that the meat be consumed on the first and second days, while any leftover portions should be incinerated, ensuring that the less fortunate are encouraged to partake in the celebration as a necessity.
