'Priests' in the Bible

"This is what the LORD of the Heavenly Armies says: "Ask the priests about what the Law says:

"If a man carries consecrated meat in the folds of his garment, and if his garment touches bread, stew, wine, oil, or any other edible thing, will these things become consecrated?"'" The priests answered, "No."

So Haggai responded, "If someone who is unclean because of contact with a dead body were to touch any of these things, would they become unclean?" The priests responded, "They would be unclean."
