'Minister' in the Bible

"They are to take a blue cloth and cover the lamp stand for the light with its lamp, lamp-snuffers, censer, and all the utensils for its oil with which they minister.

Then they are to take all the utensils for service with which they minister at the sanctuary, set them on the blue cloth, cover them with the leather-dyed skin covering, and then set them on the beams for transport.

Then they are to put all the instruments with which they minister there trays, forks, shovels, bowls, and all the utensils of the altar. They are to spread over it a leather-dyed skin covering and then insert its poles.

He may minister to his brothers at the Tent of Meeting by keeping watch, but he is not to engage in service. This is how you are to act with respect to the obligations of the descendants of Levi."

Is it such an insignificant thing to you that the God of Israel has separated you from the Israelis to draw you to himself, appointing you to do the work of the tent of the LORD and to stand before the community to minister to them?

Moreover, bring your brothers from your father's tribe of Levi with you, so they may join you and minister to you while you and your sons with you stand in the presence of the Tent of Testimony.
