'Ministered' in the Bible

Nadab and Abihu died before the Lord when they offered strange fire before the Lord in the wilderness of Sinai, and they had no children. So Eleazar and Ithamar ministered as priests in the presence of Aaron their father.

Their responsibilities included the ark, the table, the lampstand, the altars, and the utensils of the sanctuary with which they ministered, the curtain, and all their service.
