Leviticus 10:12

Moses repeateth and re-enforceth the former command, partly lest their great loss and grief should cause them to forget or neglect their meat prescribed them by God, which abstinence would have been both a signification of their sorrow, which God had forbidden them, and a new transgression of a Divine precept; and partly to encourage them to go on in their holy services, and not to be dejected for the late severity, as if God would no more accept them or their sacrifices.
