Hebrews 5:5-8

In the same way, Christ did not exalt himself to become a high priest, but God who said to him, You are my Son; today I have become your Father, also says in another place, You are a priest forever according to the order of Melchizedek. During his earthly life, he offered prayers and appeals with loud cries and tears to the one who was able to save him from death, and he was heard because of his reverence. Although he was the Son, he learned obedience from what he suffered.
