'Levitical' in the Bible
They brought up the ark and the tent of meeting and all the holy utensils which were in the tent; the Levitical priests brought them up.
and all the Levitical singers, Asaph, Heman, Jeduthun, and their sons and kinsmen, clothed in fine linen, with cymbals, harps and lyres, standing east of the altar, and with them one hundred and twenty priests blowing trumpets
Moreover, Jehoiada placed the offices of the house of the Lord under the authority of the Levitical priests, whom David had assigned over the house of the Lord, to offer the burnt offerings of the Lord, as it is written in the law of Moses—with rejoicing and singing according to the order of David.
Then the Levitical priests arose and blessed the people; and their voice was heard and their prayer came to His holy dwelling place, to heaven.
