'Law' in the Bible

The descendants of Levi who accept the priesthood have a commandment in the Law to collect a tenth from the people, that is, from their own brothers, even though they are also descendants of Abraham.

Now if perfection could have been attained through the Levitical priesthood for on this basis the people received the Law what further need would there be to speak of appointing another kind of priest according to the order of Melchizedek, not one according to the order of Aaron?

When a change in the priesthood takes place, there must also be a change in the Law.

since the Law made nothing perfect, and a better hope is presented, by which we approach God.

For the Law appoints as high priests men who are weak, but the promised oath, which came after the Law, results in a Son who is eternally perfect.

Now if he were on earth, he would not even be a priest, because other men offer the gifts prescribed by the Law.

For after every commandment in the Law had been spoken to all the people by Moses, he took the blood of calves and goats, together with some water, scarlet wool, and branches of hyssop, and sprinkled the scroll and all the people,

In fact, under the Law almost everything is cleansed with blood, and without the shedding of the blood there is no forgiveness.

For the Law, being only a reflection of the blessings to come and not their substance, can never make perfect those who come near by the same sacrifices repeatedly offered year after year.

In this passage he says, "You never wanted or took delight in sacrifices, offerings, burnt offerings, and sin offerings," which are offered according to the Law.

Anyone who violates the Law of Moses dies without mercy "on the testimony of two or three witnesses."
