And,

“You, Lord, laid the foundation of the earth in the beginning,
And the heavens are the works of Your hands;

For if the message given through angels [the Law given to Moses] was authentic and unalterable, and every violation and disobedient act received an appropriate penalty,

But solid food is for the [spiritually] mature, whose senses are trained by practice to distinguish between what is morally good and what is evil.

It is true that those descendants of Levi who are charged with the priestly office are commanded in the Law to collect tithes from the people—which means, from their kinsmen—though these have descended from Abraham.

Now if perfection [a perfect fellowship between God and the worshiper] had been attained through the Levitical priesthood (for under it the people were given the Law) what further need was there for another and different kind of priest to arise, one in the manner of Melchizedek, rather than one appointed to the order of Aaron?

For when there is a change in the priesthood, there is of necessity a change of the law [concerning the priesthood] as well.

(for the Law never made anything perfect); while on the other hand a better hope is introduced through which we now continually draw near to God.

Now if He were [still living] on earth, He would not be a priest at all, for there are priests who offer the gifts [to God] in accordance with the Law.

For when every commandment in the Law had been read by Moses to all the people, he took the blood of the calves and goats [which had been sacrificed], together with water and scarlet wool and with a bunch of hyssop, and he sprinkled both the scroll itself and all the people,

In fact under the Law almost everything is cleansed with blood, and without the shedding of blood there is no forgiveness [neither release from sin and its guilt, nor cancellation of the merited punishment].

For since the Law has only a shadow [just a pale representation] of the good things to come—not the very image of those things—it can never, by offering the same sacrifices continually year after year, make perfect those who approach [its altars].

After saying [in the citation] above, “You have neither desired, nor have You taken delight in sacrifices and offerings and whole burnt offerings and sacrifices for sin” (which are offered according to the Law)

Anyone who has ignored and set aside the Law of Moses is put to death without mercy on the testimony of two or three witnesses.
