Hebrews 5:1-6 NIV

[1] Every high priest is selected from among the people and is appointed to represent the people in matters related to God, to offer gifts and sacrifices for sins. [2] He is able to deal gently with those who are ignorant and are going astray, since he himself is subject to weakness. [3] This is why he has to offer sacrifices for his own sins, as well as for the sins of the people. [4] And no one takes this honor on himself, but he receives it when called by God, just as Aaron was. [5] In the same way, Christ did not take on himself the glory of becoming a high priest. But God said to him, “You are my Son; today I have become your Father.” [6] And he says in another place, “You are a priest forever, in the order of Melchizedek.”
