FOR EVERY high priest chosen from among men is appointed to act on behalf of men in things relating to God, to offer both gifts and sacrifices for sins.
He is able to exercise gentleness and forbearance toward the ignorant and erring, since he himself also is liable to moral weakness and physical infirmity.
So too Christ (the Messiah) did not exalt Himself to be made a high priest, but was appointed and exalted by Him Who said to Him, You are My Son; today I have begotten You; [Ps. 2:7.]
In the days of His flesh [Jesus] offered up definite, special petitions [for that which He not only wanted but needed] and supplications with strong crying and tears to Him Who was [always] able to save Him [out] from death, and He was heard because of His reverence toward God [His godly fear, His piety, in that He shrank from the horrors of separation from the bright presence of the Father].
And, [His completed experience] making Him perfectly [equipped], He became the Author and Source of eternal salvation to all those who give heed and obey Him, [Isa. 45:17.]
Concerning this we have much to say which is hard to explain, since you have become dull in your [spiritual] hearing and sluggish [even slothful in achieving spiritual insight].
For even though by this time you ought to be teaching others, you actually need someone to teach you over again the very first principles of God's Word. You have come to need milk, not solid food.
For everyone who continues to feed on milk is obviously inexperienced and unskilled in the doctrine of righteousness (of conformity to the divine will in purpose, thought, and action), for he is a mere infant [not able to talk yet]!
But solid food is for full-grown men, for those whose senses and mental faculties are trained by practice to discriminate and distinguish between what is morally good and noble and what is evil and contrary either to divine or human law.
