'Fat' in the Bible
Solomon also dedicated the middle of the court in front of the LORD's Temple by offering there burnt offerings and fat from peace offerings because the bronze altar that Solomon had made could not contain the burnt offerings, grain offerings, and fat portion offerings.
Furthermore, there were also many burnt offerings, fat from peace offerings, and drink offerings. And that's how the service of the Lord's Temple was restored.
After this, because the priests, who were descendants of Aaron, were busy offering the burnt offerings and fat portions until evening, the descendants of Levi prepared the Passover for themselves and their fellow-descendants of Aaron, the priests.
