'Fat' in the Bible

Yea, before they burnt the fat, the priest's servant came, and said to the man that sacrificed, Give flesh to roast for the priest; for he will not have boiled flesh of thee, but raw.

And if the man said unto him, They will surely burn the fat first, and then take as much as thy soul desireth; then he would say, Nay, but thou shalt give it me now: and if not, I will take it by force.

Wherefore kick ye at my sacrifice and at mine offering, which I have commanded in my habitation, and honorest thy sons above me, to make yourselves fat with the chiefest of all the offerings of Israel my people?

And Samuel said, Hath Jehovah as great delight in burnt-offerings and sacrifices, as in obeying the voice of Jehovah? Behold, to obey is better than sacrifice, and to hearken than the fat of rams.
