1 Samuel 2:15-17

15Also 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 sodden flesh of thee, but raw.

16And if any man said unto him, Let them not fail to burn the fat presently, and then take as much as thy soul desireth; then he would answer him, Nay; but thou shalt give it me now: and if not, I will take it by force.1

17Wherefore the sin of the young men was very great before Yhwh: for men abhorred the offering of Yhwh.
