Hebrews 5:12-14

12For though by this time you ought to be teachers, you need someone to teach you again a  the basic principles of the oracles of God. You need b  milk, not solid food, 13for everyone who lives on milk is unskilled in the word of righteousness, since he is c  a child. 14But solid food is for d  the mature, for those who have their powers e  of discernment trained by constant practice to distinguish good from evil.
