Hebrews 5:12-14

MLV(i) 12 For you also ought to be teachers by now because of the time, but you again have need of one to teach you what are the fundamental principles of the beginning oracles of God, and have become ones having need of milk and not of solid nourishment. 13 For everyone who partakes of milk is inexperienced of the word of righteousness; for he is an infant. 14 But solid nourishment is for the mature ones, from those who, through their habit, have had their senses exercised to the discerning of both good and evil.
