Hebrews 5:12-14  English Standard Version

¹² For 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, ¹³ for everyone who lives on milk is unskilled in the word of righteousness, since he is ^(C)a child. ¹⁴ But 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.
