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.
10:12-20 Afflictions should rather quicken us to our duty, than take us from it. But our unfitness for duty, when it is natural and not sinful, will have great allowances made for it; God will have mercy, and not sacrifice. Let us profit by the solemn warning this history conveys. When professing worshippers come with zeal without knowledge, carnal affections, earthly, light, vain, trifling thoughts, the devices of will-worship, instead of the offering of soul and spirit; then the incense is kindled by a flame which never came down from heaven, which the Spirit of a holy God never sent within their hearts.
