Hebrews 5:12
Verse 12 of 14. The 5th of 13 chapters in Hebrews, in The General Letters.
8though he was a Son, yet learned obedience by the things which he suffered.
9Having been made perfect, he became to all of those who obey him the author of eternal salvation,
10named by God a high priest after the order of Melchizedek.
11About him we have many words to say, and hard to interpret, seeing you have become dull of hearing.
12For although by this time you should be teachers, you again need to have someone teach you the rudiments of the first principles of the revelations of God. You have come to need milk, and not solid food.
13For everyone who lives on milk is not experienced in the word of righteousness, for he is a baby.
14But solid food is for those who are full grown, who by reason of use have their senses exercised to discern good and evil.
