'Priest's' in the Bible

And the priests' custom with the people was, when any man sacrificed a sacrifice, the priest's servant came, when the flesh was cooked, with a flesh-hook of three prongs in his hand;

Even before they burned the fat, the priest's servant came, and said to the man that sacrificed, Give flesh to roast for the priest, and he will not accept sodden flesh of thee, but raw.
