'According to the Law' in the Bible

And those indeed of the sons of Levi, who receive the priesthood, have a commandment according to the law to take tithes of the people, that is, of their brethren, though they came out of the loins of Abraham:

who is made not according to the law of a temporary command, but according to the power of an endless life.

For if He were on earth, He could not be a priest, seeing there are priests already that offer gifts according to the law:

for when every command was spoken according to the law, by Moses to all the people, he took the blood of calves and goats, with water and scarlet wool, and hyssop, and sprinkled the book and all the people,

And according to the law almost all things are purified with blood; and without shedding of blood there is no remission.
