'Needs' in the Bible

They are to take care of his needs and the needs of the whole congregation at the Tent of Meeting by performing duties at the tent.

They are to take charge of the utensils at the Tent of Meeting and meet the needs of the Israelis by performing duties on behalf of the tent.

In front of the tent and east of the Tent of Meeting, Moses, Aaron, and Aaron's sons encamped facing the east. They were tasked to perform the duties of the sanctuary and care for the needs of the Israelis. Any unauthorized person who approached was to be executed.
