Hebrews 5:8-14

8 although he was the Son of God, yet he learned obedience by the things which he suffered;
9 and being made perfect, he became the author of eternal saving health unto all those that hearken unto him,
10 named by God high priest after the order of Melchisedec.
11 Of whom we have many things to say and difficult to declare, seeing ye are hard of hearing.
12 For you should now be teaching others, if we look at the time, yet you need to be taught again which are the first elements of the oracles of God and are become such as have need of milk, and not of strong food.
13 For any one that uses milk is not qualified in the word of righteousness, for he is a babe.
14 But strong food belongs to those that are perfect, even those who by reason of use have their senses exercised to discern both good and evil.
