NASB: and the custom of the priests with the people. When any man was offering a sacrifice, the priest's servant would come while the meat was boiling, with a three-pronged fork in his hand.
KJV: Also 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.
NASB: Also, before they burned the fat, the priest's servant would come and say to the man who was sacrificing, "Give the priest meat for roasting, as he will not take boiled meat from you, only raw."
