'Levitical' in the Bible

"{And then} {when he is sitting} on the throne of his kingdom, then he shall write for himself a copy of this law on a scroll {before} the Levitical priests.

"And there shall not be for the Levitical priests, the whole tribe of Levi, a plot of ground and an inheritance with Israel, [rather] they may eat an offering made by fire [as] their inheritance, for Yahweh.

and they commanded the people: "When you see the Levitical priests carrying the ark of the covenant of Yahweh your God you must set out from your place and go after it.

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}.

And you must give to the Levitical priests who [are] from the offspring of Zadok, the [ones] [coming] near me," {declares} the Lord Yahweh, "to serve me, a bull, {a calf} as sin offering.

But the Levitical priests, the descendants of Zadok, who cared for the responsibility of my sanctuary {when the Israelites went astray} from me, they will approach me to serve me, and they will stand {before me} to offer to me fat and blood," {declares} the Lord Yahweh.

Thus if perfection was through the Levitical priesthood, for on the basis of it the people received the law, what further need [is there] for another priest to arise according to the order of Melchizedek and not said to be according to the order of Aaron?
