'Minister' in the Bible
At that time the Lord set apart the tribe of Levi to carry the ark of the covenant of the Lord, to stand before the Lord to serve Him and to bless in His name until this day.
Be careful that you do not neglect the Levite [who serves God] as long as you live in your land.
Also you shall not neglect the Levite who is within your [city] gates, for he does not have a share [of land] or an inheritance among you.
The man who acts presumptuously and insolently by not listening to the priest who stands there to serve the Lord your God, nor to the judge, that man shall die; so you shall remove the evil from Israel.
For the Lord your God has chosen him, him and his sons from all your tribes, to stand and serve in the name of the Lord forever.
then he shall serve in the name of the Lord his God, like all his fellow Levites who stand there before the Lord.
Then the priests, the sons of Levi, shall approach, for the Lord your God has chosen them to serve Him and to bless in the Name (Presence) of the Lord; and every dispute and every assault (violent crime) shall be settled by them.
