'Fat' in the Bible
Moreover Solomon hallowed the middle of the court that was before the house of Jehovah; for there he offered the burnt-offerings, and the fat of the peace-offerings, because the brazen altar which Solomon had made was not able to receive the burnt-offering, and the meal-offering, and the fat.
And also the burnt-offerings were in abundance, with the fat of the peace-offerings, and with the drink-offerings for every burnt-offering. So the service of the house of Jehovah was set in order.
And afterward they prepared for themselves, and for the priests, because the priests the sons of Aaron were busied in offering the burnt-offerings and the fat until night: therefore the Levites prepared for themselves, and for the priests the sons of Aaron.
