'Fat' in the Bible
Since the bronze altar that Solomon had made could not accommodate the burnt offering, the grain offering, and the fat of the fellowship offerings, Solomon first consecrated the middle of the courtyard that was in front of the Lord’s temple and then offered the burnt offerings and the fat of the fellowship offerings there.
Furthermore, the burnt offerings were abundant, along with the fat of the fellowship offerings and with the drink offerings for the burnt offering.So the service of the Lord’s temple was established.
Afterward, they made preparations for themselves and for the priests, since the priests, the descendants of Aaron, were busy offering up burnt offerings and fat until night. So the Levites made preparations for themselves and for the priests, the descendants of Aaron.
