'Priests' in the Bible

Thus saith Jehovah of hosts: Ask now the priests concerning the law, saying,

If one bear holy flesh in the skirt of his garment, and with his skirt do touch bread, or pottage, or wine, or oil, or any food, shall it become holy? And the priests answered and said, No.

Then said Haggai, If one that is unclean by reason of a dead body touch any of these, shall it be unclean? And the priests answered and said, It shall be unclean.
