5 So also Christ glorified not himself to be made a high priest; but he that said unto him, Thou art my Son, today have I begotten thee.
6 As he saith also in another place, Thou art a priest forever after the order of Melchizedek.
7 (Who in the days of his flesh, when he had offered up prayers and supplications with strong crying and tears unto him that was able to save him from death, and was heard in that he feared;
8 Though he were a son, yet learned he obedience by the things which he suffered.)
9 And being made perfect, he became the author of eternal salvation unto all them that obey him;
10 Called of God a high priest after the order of Melchizedek.
11 Of whom we have many things to say, and hard to be uttered, seeing ye are dull of hearing.
12 For when for the time ye ought to be teachers, ye have need that one teach you again which be the first principles of the oracles of God; and are become such as have need of milk, and not of strong meat.
13 For everyone that useth milk is unskillful in the word of righteousness; for he is a babe.
14 But strong meat belongeth to them that are of full age, even those who by reason of use have their senses exercised to discern both good and evil. *The 7th and 8th verses allude to Melchizedek, and not to Christ.
