Leviticus 10:19

Aaron said unto Moses Though Moses expostulates only with Eleazar and Ithamar, yet Aaron, taking the reproof to himself, makes an apology in his own and their behalf, the amount of which is, that he and his sons had performed the substance of their duty, offering the people's sin- offering and burnt-offering in all respects according to the divine direction; only as to eating their share of the sin-offering, the death of his sons, happening at that juncture, had so overwhelmed him with grief, that he judged himself unfit for feasting at God's table: Such things, says he, have befallen me; and if I had eaten the sin-offering to-day, should it have been accepted? Would God have been pleased with me if, in such heaviness and dejection, I had eaten the sacrifice? My sorrows unfitted me for that service; it being the voice of nature as well as of religion, that men ought to celebrate feasts upon joyous occasions, and with a cheerful heart, (Deuteronomy 12:7,) and not eat holy things in their mourning, Deuteronomy 26:14.
