'Attendant' in the Bible

Now the priests would always treat the people in the following way: Whenever anyone was making a sacrifice, while the meat was boiling, the priest's attendant would come with a three-pronged fork in his hand.

Even before they burned the fat, the priest's attendant would come and say to the person who was making the sacrifice, "Hand over some meat for the priest to roast! He won't take boiled meat from you, but only raw."
