Hebrews 5:8-14

Amplified Bible

⁸ Although He was a Son [who had never been disobedient to the Father], He learned [active, special] obedience through what He suffered. ⁹ And having been made perfect [uniquely equipped and prepared as Savior and retaining His integrity amid opposition], He became the source of eternal salvation [an eternal inheritance] to all those who obey Him,^{(A) 10} being designated by God as High Priest according to the order of ^[a]Melchizedek.^(B)

¹¹ Concerning this we have much to say, and it is hard to explain, since you have become dull and sluggish in [your spiritual] hearing and disinclined to listen. ¹² For though by this time you ought to be teachers [because of the time you have had to learn these truths], you actually need someone to teach you again the elementary principles of God’s word [from the beginning], and you have come to be continually in need of milk, not solid food. ¹³ For everyone who lives on milk is [doctrinally inexperienced and] unskilled in the word of righteousness, since he is a spiritual infant. ¹⁴ But solid food is for the [spiritually] mature, whose senses are trained by practice to distinguish between what is morally good and what is evil.
