5So also Christ did not exalt Himself to be made a high priest; but God said to Him, “You are My Son, today I have begotten You. (become Your Father).”(Ps.2:7) 6And as He also says in another place, “You are a Priest forever, after the order of Melchizedec” (Ps.110:4); 7During the days of Jesus’s earthly life, He offered up prayers and petitions with fervent cries and tears to the One Who could save Him from death, and He was heard because of His deep reverence for God. 8Even though Jesus was a Son, He learned obedience by the things which He suffered; 9And in this way, God qualified Him as a perfect High Priest, and He became the Author and Source of eternal salvation for all who obey Him, 10Having been so designated by God a High Priest after the order of Melchizedec. (Gen.14:18)

11About Whom we have much to say, but it is hard to make it clear to you because you are spiritually dull and no longer try to understand. 12In fact, by this time you ought to be teachers, but you need someone to teach you again the fundamental truths of the word of God. You have become like infants in need of milk, and cannot take solid food. 13For anyone that lives on milk is infantile, inexperienced in the word of righteousness. 14But solid food is for the mature, those who by constant training and exercise have honed their skills for discerning between good and evil.
