Hebrews 5
1For every high priest, taken from among people, is appointed on behalf of people in matters relating to God, to offer both gifts and sacrifices for sins. 2He can deal gently with the ignorant and wandering, since he too is clothed in weakness. 3Because of that weakness, he must offer sacrifices for his own sins just as for those of the people. 4And no one takes this honor for himself, but receives it when called by God, just as Aaron was.
5So also Christ did not glorify himself by becoming high priest, but the one who said to him, “You are my Son; today I have fathered you,” did. 6Just as he also says in another place, “You are a priest forever according to the order of Melchizedek.” 7In the days of his flesh, he offered prayers and pleas with loud cries and tears to the one able to save him from death, and he was heard because of his reverence. 8Although he was a Son, he learned obedience through what he suffered. 9And having been brought to completion, he became the source of eternal salvation for all who obey him, 10designated by God as high priest according to the order of Melchizedek.
11We have much to say about this, and it is hard to explain, since you have become sluggish in hearing. 12For though by this time you ought to be teachers, you again need someone to teach you the first elements of God's oracles. You have come to need milk, not solid food. 13For everyone who lives on milk is inexperienced in the word of righteousness, since he is an infant. 14But solid food is for the mature, whose senses have been trained by practice to distinguish good from evil.
