Hebrews 7:15-19

And this becomes even more clear when we see that another priest comes who is like Melchizedek. He was not made a priest by human rules and laws but through the power of his life, which continues forever. It is said about him, “You are a priest forever, a priest like Melchizedek.” The old rule is now set aside, because it was weak and useless. The law of Moses could not make anything perfect. But now a better hope has been given to us, and with this hope we can come near to God.
