'Priest's' in the Bible

And the priests' custom with the people was, that, when any man offered sacrifice, the priest's servant came, while the flesh was in seething, with a fleshhook of three teeth in his hand;

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.
