Leviticus 9:10
“but the fat, and the kidneys, and the cover from the liver of the sin offering, he burned upon the altar; as Yahweh commanded Moses.”
What does Leviticus 9:10 mean?
In the sacrificial system, certain internal organs were considered especially sacred and were to be burned on the altar as an offering to God, while other parts could be eaten by the priests. This practice of burning the fat and organs wasn't about waste, but about setting apart what was believed to be the life-center of the animal as holy. Aaron is following these detailed instructions precisely, which shows both his obedience and the care with which the Israelites approached their worship. Even in these ancient rituals, there's something worth noticing: faithfulness to God's instructions mattered, and the specifics of how we approach God were taken seriously.
