'Minister' in the Bible

so that the priests could not stand to minister by reason of the cloud: for the glory of Jehovah filled the house of God.

And he appointed, according to the ordinance of David his father, the courses of the priests to their service, and the Levites to their offices, to praise, and to minister before the priests, as the duty of every day required; the doorkeepers also by their courses at every gate: for so had David the man of God commanded.

But let none come into the house of Jehovah, save the priests, and they that minister of the Levites; they shall come in, for they are holy: but all the people shall keep the charge of Jehovah.

And when they had made an end, they brought the rest of the money before the king and Jehoiada, whereof were made vessels for the house of Jehovah, even vessels wherewith to minister and to offer, and spoons, and vessels of gold and silver. And they offered burnt-offerings in the house of Jehovah continually all the days of Jehoiada.

My sons, be not now negligent; for Jehovah hath chosen you to stand before him, to minister unto him, and that ye should be his ministers, and burn incense.

And Hezekiah appointed the courses of the priests and the Levites after their courses, every man according to his service, both the priests and the Levites, for burnt-offerings and for peace-offerings, to minister, and to give thanks, and to praise in the gates of the camp of Jehovah.
