'Ministers' in the Bible

Yet they shall be ministers in my sanctuary, having charge at the gates of the house, and ministering to the house: they shall slay the burnt offering and the sacrifice for the people, and they shall stand before them to minister unto them.

The holy portion of the land shall be for the priests the ministers of the sanctuary, which shall come near to minister unto the LORD: and it shall be a place for their houses, and an holy place for the sanctuary.

And the five and twenty thousand of length, and the ten thousand of breadth, shall also the Levites, the ministers of the house, have for themselves, for a possession for twenty chambers.

Then said he unto me, These are the places of them that boil, where the ministers of the house shall boil the sacrifice of the people.
