'Levitical' in the Bible

And they brought up the ark, the tent of assembly, and all the holy objects that [were] in the tent; the Levitical priests brought them up.

and all the Levitical singers--Asaph, Heman, Jeduthun, their sons, their brothers, dressed [in] fine linen, with cymbals, harps, and stringed instruments--[they] were standing to the east of the altar. And with them outside [were] one hundred and twenty priests [who were] trumpet blowers.

And Jehoiada placed appointees [at] the house of Yahweh under the hand of the Levitical priests whom David had allotted to the house of Yahweh to offer burnt offerings to Yahweh as was written in the law of Moses, with joy and with song, according to the {order of David}.
