John Wesley on Leviticus 10:12

Eat it - Moses repeats the command, partly lest their grief should cause them to neglect their meat prescribed 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, as if God would no more accept them or their sacrifices.
