'Services' in the Bible

The chief of all the leaders of the descendants of Levi was Aaron the priest's son Eleazar. He was assigned to oversee those who were in charge of the services of the sanctuary.

The duties of the caretakers from the descendants of Merari included the boards of the tent, its bars, crossbars, sockets, all its utensils for their services,

the pillars around the courtyard, their sockets, their pegs, their ropes, and all the utensils for all their services. Assign the utensils by name to each person whose responsibility it will be to carry them.

They are to join you to maintain services related to the Tent of Meeting, for all the responsibilities involved with the tent. But no unauthorized person is to approach you.

Take care of the sanctuary and the services of the altar so that there won't be any more wrath on the Israelis.

Now you and your sons with you are to maintain your priestly duties and all matters that concern the altar and what is housed within the veil. You are to perform these services. I'm giving you the priesthood as a gift of service, but any unauthorized person who approaches is to be put to death."

As to the descendants of Levi, certainly I've given all the tithes in Israel as their inheritance in return for their services that they perform at the Tent of Meeting.

You and your household may eat it anywhere, because it's a reward to you in return for your services at the Tent of Meeting.
